There is no point in doing Anki if you're going to lie to yourself. If you don't understand the card, hit 1. Now if the answer was antibiotics and you said penicillin, give it to yourself, you know what I mean. The point is to understand the material not memorize all of AnKing verbatim.
It's REAL tough. I found doing Pomodoros (25 minutes then 5 off) and doing 100 cards every 25 minutes keeps me on track. The thing is, if you spend like 30 seconds trying to remember a card you don't know anyway, that's 30 seconds wasted. So fly through those suckers.
The alternative though is me trying to review everything for a med school final. Or for step 1. Which sounds impossible without Anki to me personally. So I just accept it and suffer. I'm hoping third year is better in this regard, I've been told there are fewer cards per day.
Also, do you have mandatory class? If so, anki during class or you won't sleep enough at night.
Also, unless you're gunning for ortho, stop worrying about all those neural tracts your PhD professors want you to memorize that aren't on step. Learn what you have to learn to make Bs and Cs on your med school exams and move on. Not everybody is going to be AOA, and that's OK, we'll still be doctors.
Also- get at least 7 hours of sleep every night or your brain won't think fast enough anyway.
