Try to narrow down your schools on the front end - I narrowed down geographically, but if you're willing to go anywhere, some have chosen based on prestigiousness of program, lowest cost, or similar prereqs.
Once you know which schools you might be interested in going to, you can make yourself a rough plan for prereqs. This probably goes without saying, but start your Bio & Chem series now. Most of the time you need 4+ semesters of each. Math also needs to be early if you need Calc for your program (& especially if you need Physics with Calc). Once you have the bones of your schedule, shoe horn in the extras (like English comp, public speaking, or economics).
Find some way to get involved in pharmacy (or as close as you can get), volunteer or work-wise. Consider getting PTCB certified - this CAN be done self-study, especially after Gen Chem II if it's similar to my experience.
Join your pre-pharm club if you can - I wish I had, based on other SDN'ers' experiences. Make contacts contacts contacts... Professors, pharmacists, you'll need 'em for letters of recommendation down the road for your application.
When you get to that point, to echo above, start early on your pharmacy application. If you can manage to be well-prepared & want to be done super early, take the PCAT in January. If you're human like the rest of us, take it in July.
Start asking for LoRs as soon as you can - PharmCAS opens in June as I understand, but that doesn't stop you from reaching out to your contacts in May to ask if they'll do it & let them know they'll get the e-mail in June. Start your personal statement early and get everyone you know to read it.
Don't get discouraged if you don't hit your timelines. Realistically, it's just fine if your application is done at the end of August / September instead of in June / July... PharmCAS doesn't even start sending them until August! It's more important to keep your GPA up & keep your pharm experience going than to squeeze in that extra class. Take squishy prereqs during Summer if you want, or just flat-out add another year to your schedule - remember, you can take classes in Fall / Spring before you matriculate into your college of pharmacy.
To do all the prereqs AND have a well-rounded application, you're going to be a busy bee for 2 years! It's possible, but I believe it's the minority that does it. I'm not even sure it would have been possible for me to score well on the PCAT after a packed first year of college, without A&P / O Chem series. Again, can be done, depending on your study skills, ability to teach yourself, and endurance.
Good luck!
