Do not take Gupta if possible.

He cares so little about teaching or students. He told us he would not respond to questions via email.

The only grades are the midterm and the final, and the class is curved. This may sound good to a lot of people, but in reality the questions were deliberately designed to trick you - with choices such as "A, B, C, A & B, A & C". The questions were often framed in an unclear manner, but you are not allowed to ask clarifying questions.

He is a completely ineffective teacher and does not implement any student - focuses teaching methods.
