FWIW, after talking to several pharmacy students, they said that 1st year is usually when people try to get on the same page academically with the sciences, so it will be the "easiest" year and the year to get involved in terms of extracurriculars or to go out and get some work experience. In fact, it was HIGHLY recommended to work part time, and balance the books. Even if it means just weekends or 10 hours per week. Because each year gets more difficult and then by that point in 2nd or 3rd year, you can hopefully be in a better position to negotiate hours. Also, you remember better what you just studied by working and applying that knowledge in various settings ie hospital or community practice. Others have also insisted that its important to join ASHP because you do get to network the most through that venue and if anything, this is the one organization you should join in pharmacy school. People have said that pharm school is do-able in terms of the work load, but that it is pretty easy to get behind. Being involved is basically something that IS recommended. You do want to get great grades of course, but compared to medical school where no one should work, people have said pharmacy is still a challenge, but there is room to squeeze in things that will help you out for either residency/jobs.
Note: I'm still in the process of interviews. So this is just the advice I have heard.
