Hope delivered from me to you, based on personal experience
* Crammed Modern History midterm content in one week, ranked first at 92%
* Crammed Ancient History midterm content in 5 days, ranked fourth at 84% (lost marks in an essay section that I didn't study for at all, got like 6/10 lol)
* Tried memorising my English Advanced essay the day before the midterm, wrote the introduction in the exam perfectly, but forgot the rest D: So I had to improvise it all based on main points that I kinda remember and the question, got 18/20.
* Tried memorising my English Advanced creative a week before the midterm, I basically remembered the first few lines but forgot everything else. Had to improvise, got 20/20.
* Improvised my EE1 creative, got 23/25.
* Same as Advanced, I remembered my introduction for my midterm EE1 essay perfectly on the day, but forgot everything else ~.~ Had to go off vaguely remembered main points, got 23/25.
So based on all this, I'm not sure which to work on first: my memorisation skills, or my time management. xD But yeah, surely if you have more than a week to the trials, then there is hope! Just stay focused.
