Don’t wait for med school. Start now. As a college science educator I can say (with some confidence) that studying like this may help you in the short-term. You may be pulling it off studying now, memorizing, regurgitating and then moving on…but unless you are studying regularly you won’t be assimilating that information and making it useful knowledge….kind of like buying a bunch of bricks to buy a house…a pile of bricks isn’t a house…you have to lay the foundation and then build on it..
Start now…start small…study for 30 minutes each night and see if it makes a difference.
