Talks about his wife, mother in-law, and dog a lot. Likes to tell stories about his trips to vietnam and about how his dog is smarter than his mother in law. Eventually, he gets to math. Cool guy, just watch out for the flying chalk, he likes to throw it.

I comprehend that he is the easiest professor in the Math department, but he does not teach well! Most of his students neglect work problems on the 202 final, moreover, he does not teach integration techniques properly either. The goal is not only to secure an A but also polish integration techniques before taking multi dimensional calculus.

The summer precalc class is fast paced and difficult, but Schwinger is the type of teacher who makes even the most boring subjects bearable.

He is not an easy A. Read his response and it will tell you that getting an A or B in his class is difficult. The problem I had in his class is that he doesn't really teach calculus which is a common problem with CCNY math profs. All he does is problems. As a result you are forced to study extremely hard to understand calculus. Take Popvassilev.

Personally, I would not take this professor without having any calculus background. He just does problems, doesn't really teach. To succeed in math, you have to understand the concepts well and learn how to apply it. Schwinger doesn't really teach the concepts which makes it harder than it already is. Students tend to just copy and memorize.

He is a real professor. He does not give so many homework but the important chapters. He teaches everything clearly and makes jokes to refresh the classroom. Just listen carefully, don't be absent minded and be with him. I wish that's enough to learn from his class. I recommend about him.

He explain clearly, review the homework before every class, point out common mistakes that students make/tips that to solve different types of questions...he is fun, give "smart questions" for students to earn extra credits. I missed this professor. I took cal-2 with him one year ago and i enjoyed his class. Unfortunately he is retired now.

The professor makes math really enjoyable with his great sense of humor. Attending lectures is a must, and the textbook comes in handy. With the help of unstuck study and the free resources, acing this class is totally doable.
