Great prof! Very nice and helpful. Homeworks were hard, but exams were easy.

Excellent lecturer, entertaining. attention to detail cumbersome at times.

Very nice man, but a bit unorganized in overall lecture plan. Tests were partial and fair. Has lots of enthusiasm for the subject material.

CRAZY AUSTRALIAN PROF! WHAT'S NOT TO LIKE??!!;) He makes frequent use of his Aussie heritage to make you laugh.You will learn a LOT in his class. He comes off as an eccentric, funny, nonetheless highly intelligent person and answers questions patiently.He does have an obsessively crazy love of math!

Not a fun class to be in if math's not your thing. We learnt barely anything that resembled calculus that i expected. We got to the integral in a class that was supposed to cover calc 1 and 2. The class focused on limit proofs, series and convergence. Dont take this class and expect an easy A.

Easily my favorite professor ever. Lectures were the best part of my day. Jokes were subtle yet timeless. (It's OK to laugh, guys) Lectures are mandatory, homework is awful, but exams are reasonable if you study EVERYTHING. Lennard wants to see you achieve, so he is willing to help. I'm a business major who never took calc, but I still earned my A.

Genuinely interested in students and teaching, his enthusiasm is unflagging. He's crazy and australian, curious, a great teacher. Tests were super-fair. If you work and learn, you do well.

He was one of my favorite professors. He makes lectures very interesting and funny, I laughed almost every single day in his class. He challenges you a lot and to do well you must be willing to study EVERYTHING in your notes and homework. I do not recommend engineers taking his calc classes as he is very theoretical. Great for math majors.

Very cool teacher...funny, connects with the students...hilarious accent that he likes to make jokes with...class is hard but very fair...class attendance is key to success because the book is not used AT ALL...

Lennard was possibly my favorite teacher last year. His class really got into the theory of calculus (I took Honors Calc 1 & 2). The homework essentially was the test, but it was never due, which gives you lots of freedom. You'll know right away if you don't like his class, and that's the time to drop it. I definitely recommend Lennard.

This is the best math class ever. I only opened the 200 dollar book three times because the entire course is based around the notes. It is mainly theoretical and you will learn a lot. Dr. Lennard was great and really helpful.

Best math class I've ever had! Lennard expects a lot from his students. His tests are hard, but he offers so much extra credit (up to 25% per test!) that it is fairly easy to get a good grade. Study your notes like mad, go to class, go to office hours, it all helps! Lennard also has a great sense of humor and really makes the class really fun.

Dr. Lennard teaches his subject very well. Honors Calculus is very different and unlike regular calculus. He knows the material very well and will gladly help during office hours. I didn't like class the first few weeks because I felt very lost. Eventually I caught on and the class was manageable if you put in the time and effort. Amusing lectures.

If you're methodical and follow every lecture you will learn so much in this class! You need to be disciplined, because although there is no graded homework to turn in, you can't wait until the final to study. He's very funny and smiles all the time, so it makes attending class very pleasant. Previous work in calculus is almost a requirement.

An entertaining eccentric ozzie!

Favorite math class ever. He's got a great sense of humor. His Calc 1&2 class is not what you'd expect; you learn integration before differentiation and there's a lot on induction. But it's really not a hard class at all as long as you keep up with the homework.

By far the best professor I have ever had. Every class I came out feeling enlightened. I attended class not because I had to but because I wanted to. His exams are slightly hard but he gives choices which allows you to choose one of two options for each of the two problems. HIGHLY RECOMMENDED!

Excellent professor, extremely clear in lecture, gives a very fair grade. The class is a lot of work but is very worthwhile. You learn a lot and will enjoy doing so. There is ample opportunity for extra credit on his exams (24% of each exam is bonus credit). Best professor I have ever had. I recommend this class to anyone interested in math.

Take a class by Chris Lennard! He makes class interesting by telling jokes you'll roll your eyes at by the end of the semester, jumping around the classroom and learning students' names. Attending reciation will test your discipline, and homework is difficult, but exams are not too difficult if you study. Stick with it - half the class dropped out.

I would highly recommend this class for math majors or anyone looking for a more in-depth treatment of calc. Yes, it is hard, but he does give generous extra credit on tests and it is a very rewarding class. I thought he was a fantastic lecturer and he is very helpful in office hours.

He's the best professor you'll have! He's funny all the time. Aussie <3 He's pretty easy to follow if you pay attention. The exams are exactly the same as the homework so DO THE HOMEWORK. Don't wait until the very end because the homework is pretty challenging. Do the homework and you will...starts with P and ends with DONKEY... Right, PASS.

By far the best and most interesting teacher I have ever had. He wants you to succeed and is very helpful and encouraging one on one. Lectures were kept interesting by his math jokes and creation of and naming of symbols for lots of theorems. Recitations were extremely helpful. DO THE HOMEWORK. Tests are almost exactly the same as the homework

Pr. Lennard may very well be the best professor I have at Pitt. Probably the best teacher I will ever have. Every time I left his class I felt enlightened; I would go so far as to say his class completely changed my outlook on the subject in a positive way. The class is tough but if you do the homework you will be able to succeed.

The best lecturer I've had. He is hilarious and a great guy. I looked forward to his lectures every day and always left feeling enlightened. It is a unique, difficult class; it is taught entirely through proofs, going into all the theory of calc 1 and 2 you could ever want. He is a very fair grader, however, and wants you to do well.

Funniest prof I've ever had. He is interested in his students and willing to help them succeed. Do ALL the homework: tests are very similar. There is extra credit available on every exam, and an A is an 85%. Average is a B- to B. Go to Lenny with any homework you don't understand. He will explain problems that are often later found on exams.

Lennard was the most entertaining lecturer I've ever had. Fantastic prof. GET READY TO WORK! Class is VERY hard. I had a 22% on my first two exams. The only reason I passed was because I passed the final. And I had a 5 on the Calc AB AP test. If you think you love math, this is your class.

Great teacher. Would recommend 0235 if you like the theoretical part of it and has already taken it in high school (BC Calc). Gives you the theoretical intuition for materials normally done in computational way. Doesn't really cover calc 2 tho, you are expected to know/self learn the computational part of calc 2. Liked his class so much i took 450

Lennard is by far the best professor I have ever had. He's hilarious and explains things in a way that is easy to understand. The material is very difficult, the average on the second exam was sub-50. If you want to pass you need to spend a lot of time reviewing his lecture notes. 85+ is an A but he doesn't curve. Would definitely take again.

Best professor I've had yet. Will be hard pressed to find another who can explain things as well as him, while being hilarious, enthusiastic, and caring. He makes you work extremely hard. You will NOT pass the class if you don't do all of the work he assigns, at least for Calc III. However as as result, you'll understand the material better others.

This class is by no means easy, but if you stay on top of the work you'll be okay. He is clearly very passionate about calculus (and if your planning on taking this class you better be too). He makes the lectures exciting and he spends most of the time joking around and throwing markers across the room, while still teaching the information well.

He's a funny and likable dude.

I got a C and a B in the first two tests. I thought i was done. And he doesn't curve. But I end up with A+ The final is rather easy. (But it require a lot of work)The class do require u know some in calc1 at least. Lots of homework and those who can manage them should be fine in the class. Like him said,&quot; this is not wrong, mate!&quot;

Dr. Lennard was my favorite professor this semester. He's engaging, hilarious, and incredibly intelligent and passionate about math. 0235 was tough, but if you put in the work, you should be fine. As in, DO THE HOMEWORKS! Trust me. Also, brush up on your basic Calc knowledge before you take this class, especially sequences and series.

Dr. Lennard is very enthusiastic about math and often makes jokes in lecture to make you smile in a morning class. He makes himself very available to students outside of class and makes sure you leave with all your questions answered. The best way to succeed in this class is to study homework problems religiously and go to office hours.

Dr. Lennard is the best professor I've had at Pitt by far. Great guy, and he gives really engaging lectures. You work at least 3 times as hard as you've worked in any other class, but at the end you learn 10 times as much as you would in any other class. Extremely difficult class, but he understands and will do whatever it takes to help.

Dr. Lennard is a fantastic professor. His sense of humor really makes lectures enjoyable, and you can tell that he really does care about his students. This class is difficult, and I can only really recommend it if you'll be willing to put more time in than you have into any other class. But if you have the time, the class is doable and rewarding.

Dr. Lennard was a fantastic professor. He made sure that everyone understood the prerequisite material, and presented new material in an engaging manner. Homework was embedded into lecture notes-so you had to go to class to get the problems. Graded on midterm and final, but the final was a project and he gave you all the help that you needed.

I loved this course; people thought it was very challenging, but as long as you try to keep up with the homework as Dr. Lennard assigns it and ask for help when you need to, everything is doable. I took the course without taking BC prior, and I learned everything as needed from this course. I would 100% recommend this course.

Math 413 + 420 in one class. Hilarious prof, pleasure to be around, greets every student by name. Went over time constantly from joking around, but lectures were super clear and informative. Lots of ungraded homework to practice proof skills, &amp; easy to get help when stumped. Lenient grading (when he got around to it), learned a ton of tough math.

Very nice professor. Interesting course content. Attendance is not mandatory and it is up to you whether or not to attend class. I didnt attend most of the lectures and still got a good grade. He sends out notes so it is easy to self-study, and I prefer this way. Anyway this class is pretty flexible as long as you keep track of things.

Professor Lennard is great. Very entertaining and engaging lectures. Since the class is only graded on three exams, it can be a bit daunting at first, but if you score well on the final, he will make that your final grade. Exams problems are pretty much all taken from homework, so do the homework and you'll be fine.

I absolutely love this man. Took a boring class and made it fun. The class is the hardest class I've ever taken. If you take it bc calc came easy to you before, this will be a big shock. put in the work. do ALL the homework. set aside hours per day dedicated to this class. graded on 2 exams and a final. don't give up hope if you fail the exams

Dr Leonard was a really great guy, but this class is HARD. Tests are not easy (but final will be if you work). Do the homeworks he gives, ask questions, and work with your classmates. I passed, but you could definitely get an A if you dedicate yourself. Hes a great guy and really wants you to do well. BUT dont come in thinking its easy, WORK.

Dr. Lennard is a gem. Consistently supportive of his students and just a phenomenal guy to chat about life with. Be aware that he likes to take his time answering questions, which can be irritating if there are multiple people in line to talk with him. Likely the hardest I have ever worked in a class, but it was absolutely worth it.

Lectures are all theory and proofs so homework and recitation is basically the only way to learn how to practically solve problems. Professor Lennard is a great guy and very accessible with office hours but his lectures sometimes feel like a fever dream.

Everything you need to know MATH0235 -This class is HARD -Go to class and recitation -Tests are taken from the homework (do ALL of the problems and tests will be easy) -If you fail the first two exams, he will make the final your final grade -Lennard is accommodating if you communicate, and work hard. -Will transform the way you think about math

Dr. Lennard is absolutely incredible! He is a kind and caring person who spreads his excitement for teaching the class every day. I took his honors calc 1+2 class, which focuses on proving things and understanding important concepts instead of just memorizing and applying formulas, and the homework/lectures are challenging and unique.

Amazing professor, really cares for his students and wants them to succeed. This is a challenging course, but definitely not the hardest math class you'll take at Pitt. Do the homeworks, as the exams will mimic homework questions or theorems proven in class.

Gives funny and enthusiastic lectures that will keep you engaged. The content is difficult since it is an accelerated course and be warned that your grade will only be depended on two midterms, one final, and one course project. Tests will not be curved either. Make sure to try the hw problems and go to to his office hours if you are struggling.

Very enthusiastic about material, always a good vibe in his lecture, uses humour to engage students. Only grades are exam1&2, course project, and final exam. Homeworks are supplementary and used to help you practice. Although i felt that most of homework problems were filler in the sense that he expects u to do them for fun.
