This professor is truly a rare individual in that he is both EXTREMELY brilliant but also able to teach the material in a way that is widely relatable. He genuinely cares about his students and goes above and beyond to make sure that he teaches in a way that is engaging, inspiring, and memorable. Take this professor if you can!!!

Super passionate about his class and chemistry. He will explain everything you need to know step by step. I definitely recommend him. If you're trying to actually learn and not just pass by, take him. His test is basically questions from your homework, so make sure you stay on top of your work. A lot of homework but definitely a great professor.

I was scared to take this class at first, but he teaches in a way that is so easy to understand. There is a lot of homework, but if you do the homework, you will do well on the test. Show all your work!!!! Professor is very available outside of class and will work with you to make sure you understand material. TAKE HIS CLASS

Best teacher I have ever taken I scored the highest in chem on my hesi exam he loves chemistry so much he can make you love it. He actually teaches and takes the time to explain everything to you. He makes things very clear and understandable. If your going to take chem I recommend him 100%

He doesnt monitor your attendance but there are quizzes at the very beginning of every class so Id be there on time. Hes available for tutoring M-Thurs and his passion for chem makes it much more fun. Best teacher Ive ever had.

Hands down the best professor ever! Take him!!!Prof. Siniscalchi is a handsome, intelligent man that is always there to help you and makes complex topics more doable than other profs. Chemistry is a hard class, yes, but an A is attainable!! :) just make sure you go to all classes and take notes & study. I highly recommend him!

Lots of homework, but he does every problem with you in class. Also has TONS of online videos that go through each problem specifically. He gives you reviews for every single exam. It's not mandatory to sit through all his lectures but if you stay, he tells you exactly what questions will be on upcoming quiz. Final is optional to replace 1 exam

I don't think I could have picked a better Chemistry professor. He explains everything in a much simpler way so it is easy to understand. He does give a lot of homework but he pulls the questions from the quizzes directly from the homework. As long as you study and show up you will get a good grade in the class. HE IS GREAT!

i was afraid to take chemistry since I had withdrew before. he was actually a really good Proffesor. I passed with a B but sometimes he was rude. he barely let us out early. no extra credit ( barely ) and Lots of homework but he has videos which make is easy. I would recommend to take him. Just get on his good side. Otherwise he can be rude.

Would take him again! Tim is the BEST at what he does! He will cover everything u need to know with enthusiasm. YOU MUST PUT IN SOME EFFORT (welcome to college)! Overall Best professor I ever had. A required 1on1 meeting 3 times a semester to make sure how he can help. Responds to emails fast. Super friendly. Always remember YOU GET TO DO IT!

He really helps. Nice and everything, really clear. Made sooooooo many videos, has an outline for the topic for every question on the exam and videos on how to do them all. Lots of videos and real life applications in the lecture. Makes sure you understand everything, would definitely take again

You can see how he teaches on YouTube, search Timothy Siniscalchi Principles of Chemistry, its the first playlist that comes up. Theres more on Blackboard when youre in the class, he made over a hundred videos for our class to help students outside of class, including videos that go over everything that will be on the test.

The questions on the tests are worded exactly the same as the questions in the homework, he just changes the numbers. Five tests, each 25 questions, gives partial credit if you show your work, had an optional final that can replace a test grade. Knew everyones name the first day of class, really loves chemistry

This guy was SO HELPFUL! He answered emails even when I sent them late the night before the test on a weekend. He made sure we knew about all the stuff the college offers like the career center, the tutoring center, free Microsoft Office, etc.. He also graded things SO FREAKIN FAST; literally had all our classes tests back in two days. AWESOME!

I loved his class! Especially the hands on things like when he introduced the metric system he brought in a liter box and a gram and kilogram weight or when we went over molecular shapes he showed how theyre formed using balloons. He was also so eager and available to help. Would totally take him again, I wish he taught my other classes

I really appreciated how organized and clear he was. Hell tell you exactly what you need to be able to do and hell show you exactly how to do it, you just have to practice and youll do great. So caring and helpful, responds to emails fast, grades stuff fast, really fair, take him

Professor S was incredible. I dont know how many hours of videos he made to help us, he always encouraged us to see him for help outside of class, he knew so many cool facts about what we discussed and he actually knew how to teach. Just make sure you do all the homework, preferably more than once; if you can do that youre good for the tests

SUCH A GOOD PROFFESSOR! He made me love chemistry. Definitely have to study a lot but hes so clear and helpful. Recommend him 100%

Great! Straight-forward you just have to study what he tells you and cant miss class. DO THE HOMEWORK, the test is almost the same. Cool stories sometimes. Goes above and beyond

Prof. S is the best! He was able to explain everything SO CLEARLY. Chemistry never made sense to me before this class, he really breaks everything down and makes it understandable. His class is also so organized, you know exactly what to study for, you just have to spend the time studying. Not an easy A, but you learn so much it's worth it

Best chemistry professor on earth! Organic chem is not easy, but he prepared 250 vids to help you understand conceptually and made vids for all HW problems. He is an AMAZING professor! Take him. He is your best option. But get ready to earn your grade. I highly recommend him. and would def take him for orgo 2. BEST PROFESSOR EVER!!!!!!!!!!!!!!!!!

Took him for Orgo 1 & 2. Really hard class. However, he made it easy by explaining everything and breaking it down to the atom, Literally! Most amazing professor I have ever had!! Must take him. His test are written and there is a quiz each week with potential to get 2 points of extra credit from HW. So about 11 quizze is all your getting graded on

Professor Tim is the best chem professor ever. Do All his HW (there are videos he made for each question, no joke) and you will do great on all the test. Tests are Literally the same thing as HW. He teaches very well and is very knowledgeable. I truly recommend him. I took him for both orgo classes and got As plus learned a lot.

He is awesome! He really enjoys teaching and is always happy to help. His videos are extremely helpful. You still need to study as organic chemistry is hard, so make sure u understand the concept of each topic, if you follow his advice will be fine.

Tim is gifted! I started CHM2210 not knowing anything about the subject, and in 2 semesters with him, following the videos and attending lectures, I can now understand complex syntheses, in a research environment (I knew way more than others). If you truly want to learn Chemistry for your career, in his class you will. Your efforts will pay off :)

So many materials and so organized. Organic is um hard duh but this guy explains things so well and works like crazy to help

Really prepared me for the HESI. Clear test outlines, videos to help with all the homework. I thought he went above and beyond

I took Prof Siniscalchi for Orgo 1 and 2 and learned a ton. You definitely have to work for it, but he is so nice and makes so many materials to help. The only people in my classes who complained were the ones who didnt study.

I was soooooo afraid to take this class but I LOVED it. It made me know I want to be a pharmaceutical chemist. I dont know how I would have EVER passed this class without all of the handouts and videos prof s made for us. Amazing.

I put off taking chemistry until my last semester. I wasnt good at it, dreaded it. I did have to work really hard, but I knew that going in; what I didn't know was how fascinating chem could be and how clearly professor sinscalachi was going to explain it. He was so organized and helpful. Not an easy A but you can tell he cares about his students.

Orgo 2 was one of the hardest classes Ive ever taken. With Prof. Siniscalchi, it was also one of the most rewarding. Use the materials he made (I couldnt believe how much stuff he provided) and definitely dont wait till the last minute or end of the semester to study. Short, frequent tests, challenging but really organized and fair

have to remember your orgo 1. after taking organic three times at different institutions, i was amazed by this professor. if you actually want to learn orgo, you won't get as much help anywhere else as you will from the materials professor siniscalchi gives you.

So much work but super organized and lots of free materials. Didn't just read off of a powerpoint like other profs I've taken for this class. Helpful dude but def have to work, hard class

I didn't like chem in high school, so I was NOT excited to take it before applying to nursing schools. BUT: I LOVED IT! Professor Timothy was the best! OR-GAN-IZED more than any teacher I've ever had

So, I actually hated this class when I took it. I kept thinking, 'why does this have to be so hard? Seriously.' It wasn't until I graduated and started taking upper-level classes at NOVA that I realized what a gem Professor Siniscalchi was and how much he cared about our success in the future. He really prepared me, and I will always be thankful.

make sure you check your email, and actually use the stuff he gives you. if you're in college to learn and you know the work that's ahead of you in orgo, he's amazing. some students in my class thought our class would be just checking boxes like high school and were in for a rude surprise

SO GOOD

wish id taken for orgo 1 would have learned so much more, gives you reaction lists study plans hw sets test outlines videos helpful helpful helpful heeeeeeeeelpfuuuuuuuul in a hard class

took him for principles of chem for pre-nursing. cool dude, 5 tests 25 questions each, homework sets n solutions, videos for everything. told cool facts sometimes. if you have the time to study, should be good

The class got harder as the semester went on, but he gives you what you need. If you are willing to study and like challenging teachers who give you what you need and are organized, he's def worth taking

Loved Professor S!! Was straight up terrified of chemistry and he made me love it. Not an easy A, but the absolute BEST

really not bad if you use the materials he gives you. straight forward. pay attn to details. it's a lot but it's orgo. he helped me a lot in office hours a couple times, but honestly the videos he made answer almost everything except for questions about how to study etc

I took Professor Siniscalchi for Organic 2. My Professor for Organic 1 was easy and at the time I loved it, but then in Organic 2 I really regretted it because I understood almost nothing. Professor Siniscalchi saved me. Hardest I ever had to work in my life, but his videos and materials allowed me to pass and even get a B.

soooooooooo organized. broke every test down, had a video for everything, broke every example down to the step. it's still chem but awesome teacher

Organic Chemistry 2 was the hardest class I took at PBSC. I just wanted to post a review on here because I wouldn't have been able to pass without the enormous amount of help and videos provided by Prof. S. Thanks so much, Professor.

I failed chem in high school and I did NOT want to take it ever again. I'm so glad I took professor sinscalachi. he was soooooo ooooorganized and had so many videos to help. also really nice, can tell he loves his job

AMAZING

wish i'd taken him for orgo 1, the guy i had did not prepare me at all. orgo's hard but i actually wanted to learn it for my major and med school. if you actually want to learn it, prof siniscalchi is the best possible professor. so much help, so clear and so organized. just gotta do the (huge amount of) work

Really organized, made lots of stuff to help students (videos for every hw exercise, test outlines, study plans, etc). Fast paced and a lot of work, maybe cause its him or maybe cause its orgo. learned a lot

I was scared to take orgo and I had to spend a lot of time studying, but what I had to study was always really clear with Prof Siniscalchi and I ended up enjoying it. His explanations were so helpful and I never felt lost, it was just a lot of work. I would recommend him if you want to learn, but not if you want an easy A without having to do much

really straight forward class. do what he says and your good. the only people in my class who did bad were the ones who didnt study. cant believe how many videos he made for the class (literally every homework prob)

Strict with class rules, attendance, due dates, etc. Provides an iiiiinsaaaaaaane amount of help (videos that go through literally every hw prob, test outlines that tell you the topic of each question and which hw questions it'll be based on, calendar for the whole semester, day-by-day study plans, etc.). most organized prof I've ever taken

really good prof, would take him again

I struggled with organic chemistry more than any other subject in undergrad. I took Orgo at two other institutions before I found Prof. S. I wish I had found him sooner. I finally understood organic. It still took hours and hours but it was actually understandable and he ended up preparing me so much for the courses I took after. Awesome Prof

really amazing prof, you just can't relax the whole semester, orgo does not stop for anybody. def unlike every other class I took at pbsc, but the prof was really incredible, made and did so much to help (but didn't give out easy a's)

I can't believe how good this professor was. I was so scared to take chemistry and he broke it down so clearly and made it really manageable. My cousin who took chemistry out of state saw all the videos and help he made and was so jealous. Tests are real but fair. I'm so glad I took him.

O Chem is tough tough tough! But this man made a craaaaaazy amount of stuff to help us students. Totally organized (never had another prof this freakin organized). Good lectures! But man oh man orgo is a lot of work, don't expect a walk in the park with o chem

I was so impressed by Professor S! He is very engaging and explains topics really clearly. He is really organized. His tests are fair and straight forward, I always knew what to study for, and the tests were always based on the homework (he has test outlines that let you know how). Has videos for everything! Great class, would highly recommend

I was so afraid to take chemistry but I took professor s and he made it so clear! he also made so many videos to help! really really organized, I wish all my professors were like this! totally recommend him, great professor!

SO GOOD!!!!!!! Made so many videos you don't have to buy a mad expensive book and the explanations are all clear!!! So glad I took him!!!! specially for such a scary class as chem

I practically went bald from the stress of how intense organic is. so it says a lot that I'm leaving this guy a good review. I recommend him if you really want to learn, but if you are looking to get through orgo without working your butt off, find someone else. fact: I feel like I understand orgo so well after this class.

My friends took Orgo 1 at FAU, which I heard was impossible, so I took it at PBSC. Honestly, I didn't think I was going to learn much, but by the end of the semester I was amazed by Prof. Siniscalchi. My FAU friends were so jealous of the videos he made. Hard and a lot of work, but it's actually possible to learn Orgo with him. So glad I took him.

good class good teach but hard to find time. it my first time in college and difficult class but hard but really good teacher

I really liked how he got us to think about concepts and understand the why of stuff rather than just memorize everything (though we def had to memorize a lot). Chem is hard for me, but the amount of effort he put in to help was very clear. would have been better if I didn't take so many classes with it, otherwise hard but awesome

made me love chem

I got a C which bummed me out, but honestly I wouldnt have passed at all without the videos and other stuff he made. I dont know how anyone has enough time to do well in orgo, but if you do, this is the best dude you could take

Amazing class! Five tests, 25 questions each, breaks down everything you need to know and has videos for it all. It takes a lot of time, so dont take if youre looking for an easy A, but if you want to learn chem I highly recommend

haaaarrrrrrrrrd. so haaaaaaarrrrrrd. still, I learned a lot. enthusiastic guy, lots of stuff to help. also really organized

I LOVED THIS CLASS! BEST, SO MANY INTERESTING REAL LIFE APPLICATIONS, DIDN'T KNOW CHEM COULD BE SO INTERESTING

class got a lot harder toward the end of the semester, but he warned us and made a lot of stuff to help. overall class was nicely done

Loved this class! I learned SO MUCH. Never thought I would have liked chemistry, take him you won't regret it. (Though of course you have to be ready to work in orgo, so make sure you have the time and use the stuff he made).

I took orgo 1 years ago, so I was really nervous to take orgo 2. it was tough but I he is really organized and makes it easy to review anything you don't know. also has videos for like everything. all in all, I'd say he's the best for orgo

I enjoyed this class because how all materials were presented and broken down. Honestly, if I knew about this professor when taken chemistry 1 and 2 I would of definitely sign up. One of the best professors I came across in my academic career.

He is very knowledgeable and able to teach the material in a way that is condusive for a novel Organic Chemistry Student. The lesson videos made by the professor were very organized and well summarized. Very easy to understand! The homework packets were also very helpful! You can clearly see the effort and dedication he put in each video explaining

I have only positive things to say about this course. His day by day study guide was helpful in keeping me on top of the material. Studying an hour or so a day is not really something someone wants to do, but it really forces you to learn the material inside and out. He did a great job

Professor Siniscalchi is one of the best professors I have ever had in my college career. He made a very difficult subject interesting, engaging, and fun. His online videos, clearly organized homework assignments, and virtual class sessions made the information easy to absorb. You have to put in work to excel, but all the tools are provided

The videos created for this class were by far the most effective thing that has ever helped me learn. This matched my learning style perfectly, and allowed me to go back to the videos again and again if i ever forgot or didn't understand something. There were nearly no videos that left me confused, which seemed impossible for organic chemistry.

I was so happy with how well organized and simple this course was set up. Everything you needed was right in front of you. Tests matched the homework. Loved this class even though it gave me a super hard time. Best teacher ever!

Orgo 2 was really tough for me. But Professor Siniscalchi was also one of the best professors Ive ever had. Hes really organized and cared enough to make a lot of materials to help, like his videos. Dont take him if you dont have time to study, but if you want to learn hes incredible.

I loved this class! I was so afraid of organic chemistry before I took Professor Siniscalchi. He broke everything down so that it was SO CLEAR!! He had so many real-world applications and gave such detailed, enthusiastic lectures. A lot of work, but such a gem!!

I have two kids and didnt know how a semester taking orgo 2 was going to go. Luckily, I took Prof. Siniscalchi. He doesnt just explain the material clearly, he gets you to think about the why of everything and see it in your life. Wish Id had him for my previous Chem classes even though it was a lot of work

prof helped me make so many connections and understand alot. cool dude, helped me find research opportunities in office hours etc.. the class is hella hard, but like its orgo so what do you expect? breaks down what you need to know for every test and has a video for everything, no joke. great lectures, too, really recommend

the Professor is a great lecturer, in a sea of boring, PowerPoint reading remote lecturers in my other classes. It was nice to have a Professor that actually cares about teaching and makes it interesting and fun.

Pros: Took his time outside of class to make very helpful videos that go along with each question of his hw packet. Made connections to real life examples to help you understand the material better. / Cons: The videos/hw are reallyyy long and time consuming. Tests are kind of tricky and synthesis heavy. Always ran out of time during class.

In order to ace the exams, you need to master the underlying concepts and spend a great amount of time reviewing practice questions and online lectures daily. However, Professor Siniscalchi is exceptionally skilled in demystifying the notoriously difficult subject of O. Chem. His course fully prepared me for the O. Chem section of the MCAT.

He is one of the best professors I have ever had. Watch his videos on how he solves problems and you can ace the class. Just study !!

This is my first time ever rating a professor and I felt the NEED to come rate professor S. He is an amazing professor! I was so scared to take him because of the mixed reviews about him but guys please do not believe any of that. He is one of the best professors I've ever had, he's extremely caring and teaches with passion. *optional homework*

I took this class fully online and the professor does a great job of making instructional videos for each topic and provides lots of practice problems. He offers extra credit for every exam along with including how many questions on a certain topic will be given on the exam. You can pass the class if you study for the tests and review thoroughly.

Prof. S is a godsend. His accessible office hours and willingness to review prior exams coupled with his own videos walking through practice problems make a class like Orgo not as daunting. Rather than scaring off pre-meds by telling them to quit, he truly wants his students to succeed and helps in any way he can. I highly recommend Prof. S.

Prof S. is THE best professor I've ever had in this college and made Orgo chem 1 and 2 the easiest subjects to comprehend. If you have any questions he will explain to you in class but I've also gotten emails from him way after class time with additional videos that helped explain more which helped a lot! I wish I could take him for every subject!

This class was a grind, but Professor Siniscalchi's teaching style and helpful lecture videos made it manageable. Unstuck AI was a lifesaver for practice problems. Tough exams, but worth the effort.
