Should we study straight from the start of the semester or relax a bit in the first few weeks and catch up later in the semester?

My experience, in Masters is to start early and be consistent.  I have tried both ways and preparation is the key to a smooth semester.  Otherwise you start to pull your hair out by week 8

I would say that it is best to start reading your literature and articles, so you would get that out of your way. Than you can concentrate on exams and assignments later down the track.
