Hi 🙂
My situation with MCAT: I took the old MCAT (January 2015) and didn't do well, so the next time I took it (April 2016) it was the new MCAT. I sucked at time management (senior year, distractions, more crappy excuses, etc etc) and suddenly there was 12 days left (I'm not even joking about this) to cram for this exam. Luckily, I was a bio major and did research on the side so at least I stayed connected to the science the whole time.
What really helped me was to set manageable goals for those 12 days and adjust my mindset.
Mindset
As I was studying, I told myself... every moment you spend studying and engaging with the material, you are moving forward. Don't allow yourself to get frustrated, even if it's going really slowly. Always think about building up instead of tearing down. Don't deduct from 528, start adding it up and head towards 528. I say this to everyone and I think it's so important - BE KIND TO YOURSELF. If you were watching a friend who was studying for the MCAT, you would never freak them out by saying "oh my goodness, you haven't studied that yet? Get on it!" so don't do it to yourself either. Be as encouraging to yourself as you would someone else.
Setting manageable goals
I found that a lot of people are bad at this, and it only became apparent when I had 12 days to study. Often times, they don't set manageable goals, they set dream goals and when they don't reach those goals it's demoralizing. Yes we'd all like to sit down for 3-4 hours at a time and cram in a lot of hard material, and maybe some of us can really concentrate for that long, but I certainly couldn't. Instead, I set my goals on the concepts I struggled with the most. I didn't really know how long it would take to learn about pitot tubes, so I didn't give myself a time limit. After I did learn the concept, I gave myself a pat on the back, took a break and did something fun, then came back to tackle the next concept.
Meditation
Before I started any chunk of studying, I gave myself 2 or 5 or 10 minutes to just sit there, close my eyes, and envision what my studying for that concept would look like. I blocked out all the things I hadn't learned yet, blocked out all the panic of all the other crap I have to do, and just focus on what I'd like to achieve in the next couple of hours. Also said a lot of encouraging phrases too - I can do this, I am capable, I have faith in myself.
Sorry that was such a long post. Not sure if that was any help, but I definitely endorse mindfulness 1000% in this whole MCAT business.
