I really want to improve my grades...
I have just finished some of my a level exams and I really recommend revising using different platforms like one day watch loads of videos on whatever you're studying, another day make mind maps and try and do little bits of all the subjects you're revising for... not like 3 hours of chemistry and 4 of biology (for example) do little bits of both... and mix it up, keep your brain active also revising is a good excuse to eat loads of carbs!! Power your brain!! GOOD LUCK!!!
Put all the info on a portable device. I used to just take my school notes in class and write them into the notes app on my iPhone. Whenever I was free I'd have them right there to look at. And if I really needed to, whip it out sneakily during a test haha. The key to studying isn't to remember everything, just to remember the important stuff:D
Always look up for stronger words on google. Instead of "the big door way" make it the Grand doorway." Always label your ideas from greatest to least. Make the secound best the top the third the midddle and the number one your closeing. Also if your not sure about something then ask another teacher to read it over for you.
You could try drawing some mind maps, writing notes on flash cards, reading your books then take notes or put notes up over your bedroom walls. You just have to see what works for you :)
Search material on the Internet , do a experiment by yourself, at the end you should write a summary.
What do you mean....?
