I just came across this thread of yours. my entrance test experience is a life long lesson. i just had one month to prepare so i gave more emphasis to biology and chemistry. this is probably the main reason why i found physics very tough. Since no calculators are allowed you have to be very adept in solving numericals and doing calculations. otherwise u will be a gonner like me. biology was totally from fsc books. chemistry was easier compared to what i had expected. but physics defeated me. calculations took most of mytime.there were too many numericals so practice problem solving mcqs. you have to be good at grammer to get through english. also seriously leave the questions u dnt know. And if u are short on time dnt join tution centres. Study by urself. Hope this helps. good luck.
