Here's some strategies"
- Study ALL subjects & revise ALL content. I cannot stress this enough. Guess what's gonna happen if you don't study the organelles that comprise of a eukocyte?? IT'S GONNA BE IN THE EXAM. So, revise everything - even if is a little bit
- Identify keywords. Unless you have some naturally-born gift, don't try & memorise masses of sentences, or worse, Paragraphs! Keywords are sufficient
- Lastly, don't rely on herbal remedies to boost memory & concentration. It's mostly all willpower & the ability to concentrate and focus on the task at hand.
Hope this helps
goodluck
