I was reading that you retain information better if you learn the material at maximum blood oxygen and glucose levels. If you did not learn the material this way, then raising those levels would not help retain the information any better. Nonetheless, I presume that the brain would function more efficiently with these 2 levels maximized. Thing is, oxygen levels peak for like 5 minutes after exercise, so the only thing that is controllable over longer periods of time is glucose levels, maybe oxygen tanks? hmm... Drinking a high glucose drink (Ultra Fuel) 30 mins before studying should help, peaking for about 1 hour and returning to baseline after about 3 hours. Glucose has been shown to increase acetylcholine levels. What do you think of drinking glucose before every section? Could that cause too much sugar in the blood? Crashing shouldn't be a problem as long as you get a break every 1.5 hours or so.

I don't think you need to get too wrapped into all of this. Just be smart about studying... make sure you've eaten well, you've got enough sleep, etc.

We're going to be taking tests for our whole lives... it's impractical to constantly be wary of oxygen and glucose levels before every exam.

1) study
2) take the exam
4) profit!!!!
