it's more than fine if you can successfully pass your classes and this will not interfere with your professional goals. I wouldn't like that schedule bc it would be mean school mon-fri then work on the weekend... sounds like one heck of a boring life. p2 and p3 of pharm school are quite stressful bc of the fast pace and weekly exams (in my school at least) so i wouldn't do it.. You will make 16 to 20 bucks per hour, i don't think it's worth the stress and opportunity cost. I'd rather enjoy my grad school experience, you have the entire life to work ahead of you for much better wages. FYI, i worked 8 hours per week most of the weeks. 24 hr-Full time work during breaks
