First of all try to reduce a lot of the things together by taking only the most important things out and writing it down on another paper. This'll give you a lot of hope because you don't have to study that much anymore, it'll make you happy to see 10 pages instead of 30. Make sure you do this a couple of months or weeks before you've got to study it. What can also be handy is trying to make sneaky notes for peaking at (I'm not telling you that you should use these at the exams but you really try to write the most important things on notes like that and you also study it a little bit). After you've done any of those two, I recommend you search for what's the best way to study something for you. You can either ask a family member for help to question you. You can explain what you have to study to someone who knows nothing or little from it. If you have a chalkboard, you may want to write it down on the board which is very handy to for languages because then you learn how to write the words and stuff. You may want to avoid any noise or prefer some music that's up to you but know that you don't have to take music that'll distract you nor make you fall asleep. Also pets and parents shouldn't be coming in and out of your room. Make sure your breaks are long enough and you drink and eat healthy. If you don't need your laptop leave it with your parents so you don't get distracted, if you do need it, turn of the internet or block some sites for a while, you will find it on the internet how to do so. DO NOT HAVE YOUR PHONE WITH YOU, you'll check every single minute if you have a message or what time it is. If you want to keep track of what time it is and when your alarm goes off use a kitchen clock or a clock (the one's you can place next to your bed to wake up). Make sure the kitchen clock isn't ticking because that'll be very annoying. Also start with the easiest things first, this is very handy because you'll know something and you'll be sure of it and you might make a lot of points on it. Leave the hard part as last because you may study a couple of things then but not everything and that's not bad because you know the easy stuff and that'll get you somewhere already. Also if you are tired, go to bed and wake up a couple of hours earlier, this gives you time to refresh things and you'll study much better. These are my tips, and tricks, I hope you understand my English, I wish you a lot of luck and I'm sure you'll do great, if you do have any problems don't bother contacting me!

I use something called the Pomodoro technique whenever I study/do homework. How it works is that you work for 25 minutes then take a 5 minute break. You do this a total of four times and then you get a long 25 minute break. So it would go like this: 25-5, 25-5, 25-5, 25-25 and the cycle repeats from the beginning. I like this technique because it helps avoid burnout for me. Here's the official website for more info.
