It depends on where your blocker is, (1) is it your approach to studying or (2) the quality of your approach.
For me most of the time I knew what to do and realized I had to solve an energy problem and didn't have a "technique" problem. Or that I was not getting enough done that day due to bad sleep the night before.
Assuming this is about studying techniques and you have energy problems covered, I recommend looking into Bloom's Taxonomy.
The best way to study is to apply what you learn, and often that is doing problems. BUT again - you need to also make sure you did the readings, you have to do both, but the feedback loop from reading AND doing the problems is the best way to study as you are able to get feedback whether you know the material or not. Reading is passive and doesn't have any feedback loop, but you also can't skip it either otherwise you are going to have foundational gaps. Now, if there is a magic method to compress it even more, I can't tell you that because I'd like to know too. But often, you have to do both and with that you'll often hit an energy wall because its a high volume of work and cognitively demanding, because me getting to bed on time has been better for studying than most "fancy techniques." Invest in good tools and systems, and make sure your environment isn't giving you brain fog (mold exposure, etc.)
