I am speaking of my own experiences, so your mileage may vary, but I find the "aural" and "visual" and "kinesthetic" learning strategies to be a bunch of bullshit. How in the fuck are you going to learn biology efficiently if you're a kinesthetic learner?
I've tried figuring this out for about 8 years. You wanna know the secret? Ask questions. We're very, VERY good at deceiving ourselves into thinking we know something. In programming, they have a way of debugging code called "rubber duck" debugging. You take a rubber duck, and explain to it what the fuck you were thinking when you wrote that code.
I'm not saying you should talk to a rubber duck, but the best way I found to retain information is to explain it, either in your head or preferably out loud, when you're alone. If you can't explain it thoroughly, or enough to make you happy, make a note of it.
After doing this technique a few times, I've actually thrown away textbooks, because they're really stupidly vague when you get down to the nitty gritty.
Of course, I'm not you, so this may not work for you. Still, it's something to try. What the hell, right?
