I studied and took the old MCAT in January so my advice not be as relevant as someone who has taken the new one. However, I too was working full-time and couldn't follow the schedules listed here. I ended up scoring very high so it's definitely possible. My advice in coming up with a reasonable schedule:
1. Decide on a date. Don't start studying without knowing when you are actually going to take it. Sign up for an actual date- if you end up having to change it, it's not that much money and it is worth it. I suggest on giving yourself about 3-4 months of studying time (unless you're learning some of the stuff for the first time). I took about 3 months and it ended up working out well but right before my exam, I did wish I had some more time.
2. Schedule some vacation time for about 2 weeks off right before your test. If you can only swing 1 week, that's still good but obviously more is better.
3. Once you have your date and time off scheduled, figure out when you want to take the practice exams. I don't know how many full length exams there are for the new test but I imagine there are plenty by now. You will want pretty much your last month or 6 weeks so to be taking practice exams, reviewing them, and brushing up on content areas you see you're weak in. The way I scheduled my practice exams was I counted back from when my actual exam was scheduled for. I knew I would have two weeks off before so I took that into account. I believe my schedule was such that I started taking one practice exam a week starting 6 weeks before and then once I got to those 2 weeks where I was off of work, I took one every few days. ****it is KEY to also schedule the time to fully review every single question (even the ones you get right!) I liked to do this immediately after each exam as it allowed me to recall my exact reasoning when I had initially chosen each question.
4. Once you've figured out a tentative practice test schedule, you can schedule your content review. For me personally, I liked doing one full subject at a time but I know other people like to do it as a mix throughout. In either case, what I suggest doing is looking at how many chapters in each subject (other than verbal) and then calculating how much you need to do each week to stay on track. Schedule more time where you know you are weak nSo for example, I knew I wanted to spend more time on physics than chemistry because I find physics harder. So I think I scheduled 3 weeks for physics and 1 week for chemistry. I looked at how many chapters were in my book for physics and figured out how much I'd have to cover each weeknight. I think it ended up being half a chapter which was totally manageable.
**also, when you are doing what I call "content" review, I suggest doing all the in-chapter problems, don't just do the reading
I literally had my schedule on the notes app on my phone - I would highly recommends writing it out. This makes it easier to see if you are keeping on track or not.
5. If you start getting off schedule, don't worry! Just readjust accordingly. As long as you are keeping track closely, it will be difficult to get derailed significantly if you correct your derailing early. For example, my job is very stressful and tiring and sometimes I would fall asleep while studying and not finish what I had scheduled myself to do. Instead of panicking, it just meant that another night I had to study more than I had initially scheduled.
As a side note, don't expect to have much of a social life and don't allow people to make you feel guilty about it. My life for those 3 months was pretty much going to work, relaxing a bit when I came home and had dinner, studying and sleeping. Saturdays were my "off " day but I still did some studying Saturday nights. Sunday's were full mcat days.
6. My job is not one that allows for downtime so I couldn't exactly study there. However, I took pictures of things on my phone and whenever I had some downtime (waiting for a meeting to start, waiting for the elevator, etc), I would pull out my phone and study the pictures. (This is literally how I memorized the hormones!) I would highly suggest doing something similar. It also had the nice effect of calming me down when I felt like I needed to be studying more.
That's all I can think of for now. Hope it's helpful!
