P1 is a really hard transition, and its tempting to think that going to another school will be easier. Whatever problems you are having at your current school, transferring schools most likely will NOT fix those problems. I strongly encourage you to buckle down and hang in there, get advice on fixing the problems you are having.
I thought this my 1st year, I suspect many students do, I thought I had made a mistake. But I stuck it out, worked to find solutions to the problems, and things got much better. Pharmacy school is hard, but it turned out to be one of the most rewarding experiences of my life. I have no regrets now, and the school I originally picked really was the perfect school for me.
Most likely, your school is the right school for you, you just have to make the adjustment.
