1. Interval Study
Much like interval training, interval study is when you study for a period of time (usually 30 minutes, for me) and then take a short break (5 minutes). When you have a lot of things to do, you might think the last thing you should be doing is wasting time on breaks (like who has time for that shit??) But, it is important to give your brain a bit of a breather once in a while. During your break, your brain will have time to refresh itself and process the information that you threw into it in the last 30 minutes.
An app I use for this is Forest (available on iOS and Android). Not only does this app notify you when you finish your mini study session, it also prevents you from getting distracted by going on your phone! (Killing two birds with one stone is always the way to go!)
2. Electronics = OFF!
I've already touched on this point above with the app Forest, but guys, it is so so so important to eliminate your distractions by turning off your electronics! It sounds obvious, but you have no idea how much it can help until you actually do it.
Sometimes, you might need to use the computer, but not the internet, in cases like that, I'd advise you to turn off the wifi. If you need the internet, then maybe look into add-ons that will ban you from using certain sites (ie. Facebook, YouTube, Twitter) for a certain amount of time. Although I don't do this, an example of this type of add-on is StayFocused.
3. Have a Plan
It's a good idea to have at least a rouch idea of what you plan to accomplish every day. For me, I make a to-do list of all the things I ideally will finish every single day for a week, when I have busy weeks (eg. read chapter 12 for chemistry and finish lab report on monday). There's an actual week of my life where I did this, and it really helps! It's also a good idea to write down due dates, so you know the maximum amount of time you have to do something.
4. Lifestyle Matters
The way you live when you're super duper busy matters, too! If you're too stressed, your preformance levels will start to drop and you won't be able to do as much as you ideally could. So, to prep yourself so that you can achieve your maximum potential, get at least 6.5 hours of sleep. (I would say get a full 8 hours, but, really, who has time for that?)
You are what you eat! Seriously! Putting junk into your body will only make you feel sluggish. Make sure you stay hydrated and fill your bodies with lots of nutrients! There are all sorts of foods that can help boost your brain power so you can get the most out of your time. Examples of these foods include avocados, blueberries, and broccoli. Read this for an explanation for what some of these foods are good for.
One last thing, IISuperwomanII recently posted a video called "5 REAL Ways to get Your Work Done" in which she outlines 5 seriously awesome strategies that we can implement into our lives when we want to get crackin'. (Seriously go watch it, it's an awesome video)
Anyways, I hope these were at least some what helpful. Do you have any tips that I didn't mention? If so, please let me know in the comments!
