I think the way I used the mid semester breaks was to a hammer home the finer details. At least, imo most people who are trying to get into med understand the broad concepts covered in most papers but what really helps you get A+ is getting the smaller details as well especially to help you with the tricky MCQ's they throw at you in 107 and medsci 142 in semester 2. Its a good idea to do the practice tests early to see if there are and major errors you struggle with so you can spend some serious time focusing on that and also to give you and idea of the questions they like to ask and then I like to go through ever lecture again and try to teach it to myself from memory and what I can't remember go through that again. Also and probably most importantly, you guys should take a break at least on Easter weekend and remember not to study for the whole holidays. Try to catch up with your friends you haven't had as much time for, spend some time with your family and just generally spend some time relaxing and unwinding from a busy and stressful few weeks. Try to take care of yourselves properly because it can be easy to get wrapped up in your goal of med, I know I certainly did at times and this will be your guys last chance to have a proper break at least till the end of semester. Enjoy your break everyone and good luck!
