I can promise you it is true for me as well. I just had to disregard all of the conventional study advise and go with works for me and that was incredibly intensive cram sessions that could literally last days nonstop. It does indeed work for me at least and I remember it quite well indefinitely. I got great grades (often the highest in the class and some even the highest ever for that class). I tried the incremental study methods and found that they were, at best, a supplement to my more intensive cramming methods.
Granted, it works much better for subjects like pure science rather than foreign languages but, even in that latter case, I found it easier to just force myself to learn to conjugate 100 verbs in a night rather than learn 3 a day for a month.
I realize that people vary greatly in this but I just roll my eyes when people claim that the more intensive methods won’t work because I know for a fact they can and do for some people including me. I wish that wasn’t my preferred style because it is stressful and exhausting when you have to hit the books with a hard deadline.
