A very good teacher in my opinion. He lectures a lot in class, he's very friendly and seems to have a passion for math He assigns hw but only two problems is required to do for each section, so the rest is optional. He gives partial credit for things both test and hw Exams are 90% homework (includes optional or required problems) 10% made from him

the best part of him is his lectures

He let the whole class do extra credit for their tests when most of the class failed. Wants people to figure things out by themselves so he won't always explain what to do step by step, but tells you why. I think that's good because you wont always have someone telling you everything in real life, and math is supposed to teach logic.

His class was great! I had never been good at math, but he explained it well. The only thing I did not like was that he would not answer some questions clearly. He wants you to REALLY think about it before explaining it. He does drop the lowest quiz scores though which helped. Overall, I would recommend him.

This class was a little harder than I had expected. The tests given were all hand written and challenging. If you work/study really hard on everything taught in class you'll be fine.

Professor Castro is the absolute best! I am not kidding! The way he explains math will make you understand everything being taught perfectly. He is patient and doesn't get irritated with his students. I took his 6 week winter course and passed with a B. No other math professor will teach 150 of any other math class better than him. Go Castro! :)

His teaching skills are amazing. He did put a lot of effort on his job. He will always teach students patiently and make sure that everyone understands the class. I enjoy his class pretty much just because i did learned a lot of methods from him.

Mr. Castro is a very good professor. Math was not my strength, but after taking this class it has changed my mind. I really enjoyed the class and I received a B. I only missed once. If you miss to many days you will get behind in class.

Castro is the best math prof i've came across. He wants all his students to pass & makes sure they learn. He gives a project, 5 tests ,& a final but drops the lowest test. He's a great prof, he knows what he's teaching. Study hard & ask questions and you'll be fine. He's great, you won't leave class w/o learning something new which is rare to find.

He is very caring and welcoming when you ask for help in class or office. He takes his time to explain in detail till you understand when you get his help in his office because he doesn't need to rush thru the problems due to long office hours. Majority of the time, his office is packed because he is nice and explains to student level.

Homework is not too bad, but he wants his students to understand the work. Study, Study, Study, do the homework, and ask questions. Overall, he is a good professor

Prof. Castro is THE BEST math professor at PCC. I had him for Math 150 and Stats 50. If you are looking for an easy A, do not take his class. However, out of all the professors I had at PCC, he is the one who prepared me the most for UCLA. Class Breakdown: 5 Exams. No study guides. No extra credit. Gives partial credit.

I took his class during winter intercession last year. The homework took me all night to do. I was exhausted from waking up early everyday but luckily we get a break each hour. With Castro, he's a funny and nice guy. He's approachable to get help with. There's a lot of work and some material was hard but I managed.

Very good professor, I like his class very much!

Castro is a real gem. I took him for math3/math 8 math path and he made me love math! His lectures are amazing and he goes out of his way to explain everything. The class itself is challenging but that's expected, however if you study an A is definitely possible.

Don't take him if you're not willing to learn and you won't get an easy A. He's really passionate about math and is always willing to help you out if you have any questions. As long as you pay attention in class and complete all your assignments you should be fine. I would definitely recommend taking his class!

I took this class in the spring 2018. He is very nice, and lectures are very clear. Tests can be a little hard, but do your homework and you will be fine. Definitely one of the best math professors I've ever had.

Very down to earth & knowledgeable but he is tough! You will learn a lot, but this class is very challenging. Some problems on the exams are straightforward from the notes, but sometimes he puts harder problems that require a lot of critical thinking and previous math knowledge. Overall he is a fair grader and drops lowest exam and quiz!!!

If you struggle with math i don't recommend taking him. But, he is a great professor to take if you plan on going further with your mathematics.

He is great at explaining new material and shows problems step by step. He is very nice and always willing to answer any student's question.

He is a professor who is passionate about math. I really disliked the aleks online homework system, very frustrating and tedious. His lectures were good but can get a bit long, though it is a ton of material to cover. Questions on tests can get tricky, but he teaches most of the stuff he tests on. Review the notes and book a few times beforehand.

His lectures were clear and concise without giving you a bunch of stuff you don't need to know. His handwriting is very legible. If you have a question, he'll work through it with you over and over until you get it.

He is a very solid professor, you can learn a lot from him. He gives good examples in lectures and tells you what is gonna be on the test, almost no surprises. If you attend his lecture and do all the homework, I think you will do great.

He is very clear in his lectures and gives examples. Will also answer your questions outside or during class, graded mainly on tests and finals. Hated the ALEKS homework which you had to pay for and was frustrating/annoying. When you get one question wrong it makes you start over, you have to get 3 in a row to finish the topic. Very time consuming

Professor Castro isnt the guy to take if youre not willing to put 100% into this course. This professor has a passion for the subject that is infectious. He gives great examples in lecture and is very clear about his expectations for you as a student. Definitely take this class, you will learn a lot.

Math is a difficult subject for me, and I had to take Math 05A almost three times, however taking his class during a winter session, I surprisingly passed with an A. His course is challenging because of Calculus, but he is a fantastic teacher who makes you passionate about math even if you dislike it.

WIN21 Graded assignments/tests super late so give yourself cushion. Tests and final was take home so no proctoring. There was ALOT of homework, spent most of my time doing homework than actual studying. Great lectures, concise enough to where you'll understand. Take him if you want to get 5C out of the way but also still learn something. Easy A

Solid math instructor that loves to teach! Very easy to approach and won't make you feel bad for not knowing/understanding. Explains things in an easy to understand way. Its math, its not easy, but he tries. 100/10 will take again.

You can tell he loves to teach! Very patient with his students.

Lots of homework. Tests were easy and if you watched the lectures and paid attention to the homework they shouldn't be that hard. Lectures were pre recorded but about 40 mins+ each time. On top of watching lectures, there's an optional (but most people go) lecture that runs an hour long. Be prepared to sit through a lot of lectures, but very clear.

He is the best teacher I have ever seen. You just need to turn in your homework and you get full credits.

Note that there's no easy math class, you have to work to pass: Pros: - good at explaining - passionate - hilarious - caring - give partial credits on exams Cons: - test is much harder than practices but doable if review bold questions of hw carefully. - lots of hw - not accessible outside of class/office hours.

Never answers emails. He is friendly.

Professor Castro is an easy grader for HW. His tests are harder than HW questions given for practice. He is a super friendly professor, and answers any question that you may have in class. CON: Not accessible through canvas emails or any form of contact outside office hours. If you have any type of question, go to his office hours.

Chill class. Pre-recorded lectures are straightforward and clearly spoken. There will be one to three sections of homework due at the end of each week. Never got my emails answered. Visit his office hour is the only way. Other than that he is actually very nice and willing to help the students. Very lenient about late work when you reach out.

Prof Castro was good. He graded 15% hw 10 discussions 15 quizzes 35 exams 25 final. There is lots of hw but discussions and quizzes stopped on week 4 (6 week course). He promised extra credit 1 quiz a week and 1 discussion a week, but no EC was offered. He grades tests lightly, but there is limited time so work fast. Lectures were good. Funny guy.

Extremely chill calc 3 class. Fully online lectures, HW, quizzes, exams. Much easier than most 4-year university calc 3 courses. Lectures are decent, but the prof does not grade fast or respond to emails. Lots of annoying HW but can be easily searched if needed. Overall, not a great prof, but very easy course for material of this level.

Video lectures are helpful and easy to understand. There is a lot of homework and the class moves at a fast pace. Tests are not difficult (similar difficulty to homework) and he is a fair grader (gives a lot of partial credit). Just make sure to manage your time well. He does not respond to emails and grades really late, but still is an easy prof.

The content of his lectures that captivated the masses but the manner in which he delivered them. Professor Castro is a master storyteller, seamlessly blending facts with anecdotes, making the subject matter come alive. A lesson in his class transforms into a gripping narrative.

Im a UCLA student. I took his class at PCC since it was cheaper and it transfers to my school. Very easy. Much easier than the professors at UCLA. I ended with a 96% on his class with not much effort. your Calc BC needs to be strong.

Math in general has never really been my strong suit, but Professor Castro is a wonderful professor who truly cares about his students. I owe my B in Stats, let alone a passing grade, to him. The tests are very straightforward and he makes concepts easy to understand. He's not a harsh grader and he gives points if you show your work. Take notes!

Easy A tbh

If taking in winter, don't take any other class! Lecture, quiz, & exam-heavy. No late HW, makeup quizzes and exams, or curve. Lowest exam score dropped. Grades generously on HW & fairly on quizzes & exams. Contrary to other reviews, I believe the HW reflects the test questions which are fair. Professor is cheerful yet serious and speaks clearly.

Professor is not bad as many people say, make sure to stay focused and pay attention and you'll be fine. Good teacher, heavy homework but homework prepares you for the test which are sometimes difficult. The final was easier than most, I highly recommend Mr. Castro as long as you're willing to commit to understanding the topics.

Honestly the class is hard from it just being stats but if you are the type of student to review and study all materials when you get back home then you'll do fine. You have to put your part in learning this on your own time. He teaches with an ipad and writes out his lessons like khan academy. Expect quizzes every week. 3 Exams.

Do not expect to hear from him outside of class and office hours, he is a busy man, and I never got an email reply throughout the semester. In spite of that, he does a lot for students. Mr. Castro lowkey portrays himself as a tough professor by saying he doesn't curve things or give extra credit. But he always looking for ways to help students.

I took Professor Castro for Math 055 an he is one of the best Professors at PCC. Math is a course that involves a lot of time and commitment. These courses are not easy. So it only makes sense that Professor Castro assigns a good amount of homework to be well prepared for his exams. Amazing Professor and I would definitely take him again.

Professor is very articulate in math. He is easy to understand and eager to answer questions. He does assign a lot of homework problems but a few hard ones from the textbook often do not make it on the tests. If you are looking to understand math and are a stem major his class is great.

He is amazing at teaching the subject\ He always includes a question that he's never taught how to do on his tests Homework is easy, he assigns a decent amount, but not too much and you only need to finish 75% of it for full points, but try to do it all anyways Take him if you want a good understanding of the subject,don't if you want an easy A

Wasn't hard to get a free version of the textbook. There is a lot of homework but it really does help you prep for exams which make up the bulk of your grade. To do well you need a strong understanding of Math 5B. This is not an easy A class you do need to put the work in.

Prof Castro is a very nice teacher, but if you don't like doing lots of homework, he might not be for you. Lectures are very clear and definitely shouldn't be skipped if you want to pass. Tests can be challenging, but reviewing homework will greatly help you go over all of the concepts on the test.

He's not for everyone and will challenge you if you're not solid on fundamentals from previous maths, but he cares about everyone's understanding of the material, so don't be afraid to ask "stupid" questions during his lectures. Take good notes and reserve time for lots of HW problems. He drops the lowest test score and two lowest quiz scores.

Professor Castro is a very passionate and well organized teacher. He was able to teach complex topics effortlessly and constantly kept me engaged. He graded tests in about a week on average. Tests make up a large portion of one's grade, but there is a dropped test and extra credit opportunity for the final. Likely my favorite math teacher in years.
