I have developed of a study habit model (untested), married with a scientifically proven, "back-door", nocturnal method of association that (I'm pretty sure) may improve your study if utilized properly. Again This model is untested. The approach for studying some of your subject topics does vary, so some of the results may vary as well.* This will require the purchase of some supplies, (nothing too expensive!) and dedicated, uninterrupted sleep.

If you're interested, message me, with what you're studying, and how long you typically study the subject topic for, and how go about studying it.
I'll write you back with instructions of how to perform the sleep aided study, how it works, and the science to back up my theory of my sleep aided study.
I'll include a flexible schedule model of study for a week to start. Then we'll see how that works out. I'll make any tweaks from there, and make a complete advised study schedule for whichever topics you request, for a month.
I'll also enclose a list of materials you need to purchase to perform the sleep aided study, (Also I will, if needed, include a list of places to shop, to gather any specific materials you would need while also being cost effective to better suit any specific course studies other than core subjects.)
* Some subjects topics may need more time to study each night, or more frequency, to equal the results of subjects topic that do not need practice.

This is open to anyone really, all I ask is you keep a record of grades before, and your grades for any subject being sleep aided a month after, and a daily log for each subjects sleep aided for a month of how well you stuck to the study program so I can kinda have some rough numbers to look at if you all don't mind
