A few months ago, I received a pre study reading list for my uni course but am unsure whether I should wait until after I start the course to begin the reading or start doing some of it now. Some of the reading suggestions are lighter than the others - for example some are very short books/ articles while the others are full books. The books listed are quite expensive so I don't think I can afford to buy or read them all. What should I do? Do I just dip in and out of what I fancy or not bother with it at all?
