I'll suggest u onething read thoroughly in an out dental board buster, during part1 exms u wl find direct questions framed from dental board buster lines, second u should be thorou wid asda papers( released+ unreleased). I am nt sure bt wat I hv heard from others generally 250-275 cut off goes. But at tyms it goes upto 325 depends on quality of paper u get and it's always comparitive marking. do read antihypertensive, asthmatic, antidepressant drugs der side effects actions etc. Since pharmac is part 2 portion bt u do get questions from dese drugs. Generally I hv seen maxm questions from dental anatomy and occlusion, U shld make sure dat u understnd those questions, logic behind occlusion questions. Arnd 9 case based questions thou simple bt little confusing, if u do well in dese questions den u can easily clear part 1. All d best!!!
