How to study...well

I was looking for interesting articles online a couple days ago when I stumbled upon one dealing with efficient and inefficient study methods. I usually don’t bother with these kind of articles because they’re not very effective and just seem bland and moot, without any real substance.
The article I read, however, struck a cord.
I spent years in middle and high school trying to figure out how I study best. All those all-nighters at my desk, bent over a chemistry book or my math homework with what was probably an empty cup of coffee to my side are all more than familiar. Battling fatigue and praying that the infamous second wing’s going to come and save you (and taking in large doses of coffee until then) was something my body got very used to. There were nights were you wouldn’t be able to distinguish me from a ghost, apart from my red, blood-shot eyes that always gave me away to my classmates the next day at school.
I like to think that all that effort was payed off. The fact is, that method of studying was not only inefficient but also detrimental to my health.
As I was reading this article, I was thinking, “this is what I like to do.” So I thought I should share. The article was a list of tips and their explanations. Here are some of them that I would recommend to anyone.
1. When you decide that it’s time to study, do so in short, but frequent sessions. The whole study-until-four AM thing it outdated and over-rated. Give yourself twenty, thirty minute sessions where you study and memorize and then go and make lunch or play basketball (what I used to do). Your brain needs time to let the information sink in. If you throw a whole bunch of facts or concepts at it all at once, chances are only a small proportion will absorb, if any at all.
2. Make sure you study when you feel you’d be productive. If you’re angry or upset, you probably shouldn’t waste your time. When you’re relaxed and in the mood for learning, the learning will be best.
3. Always review. I remember AP biology class in high school; I would read something quickly and move on, not always paying full attention to my reading. Then I would remember that I read something but couldn’t quite remember what it was. Right then and there, I would look it up. That’s how the human brain works; it can’t be fully attentive all the time.
4. Prepare your study environment. Find the place where you study best, whether it be the kitchen or at your desk. Have a pack of cheez-its by your side or any snack you like. Being in the right environment is half the battle, so they say. Also, it’s been proven that chewing on something while your studying boosts concentration.
These all seem like they should be intuitive to every student, but they’ve evaded me for a long time. Hopefully they’ll be of some help.
