How to Crack the Paper
The professor repeats a lot of questions from the previous year paper. Class notes are more than sufficient to prepare for exam. But the slides as mentined earlier do not have much content in it. Attend the classes when he is taking an example from reaseach papers because there will surely be questions from that part. You cannot find these answers on google easily.
Classroom resources
Slides and handouts will be provided by the professor. But the handouts have too much information ( which will not be useful in exam) and the slides have very less information( which is useful in exmas). He willnot deregister you but can fail you.
