Yet, the undergraduate students often find it to be very tough and demanding. The need is to clarify the concepts to the students. If the concepts are simplified for them, it’s like a cakewalk.
Reading the textbooks after this would also be easier. Moreover it is the concept that matters and not just mugging up the dates, objectives, rates etc.
The website: www.ihatepsm.com has been planned with this purpose.
