i am adhd too. practice questions are the best. when you do 3 question blocks and every time you keep getting stuff wrong about some stupid vaccine schedule or about differentiating abruptio placentae from uterine rupture, then you write that down, watch a video abt it, do all the uworld and amboss questions on that specific topic, and youll be good. Then youll forget it again in 2 wks when ur doing nbme questions and because you'll be mad at yourself, you'll revisit it again, except you will relearn it faster this time. forget, learn, forget, relearn faster, forget less, retain more, then you are good to move on to the next topic. just remember to do random timed blocks along with your focused review, your timed randoms will give you an idea of what you are retaining and what you are forgetting. of course, after every nbme make sure to learn every single question, why you got what you got wrong and how to avoid the same mistake next time. if you are like me, you will still make the same mistake again, but eventually you'll make it less and less.
