I’ll the first (and possibly only) one to say there is a great difference between an A and A*. Perhaps there is no formula to getting an A* - it comes with raw skill, as most teachers will tell you. But in this context – the IGCSEs – as long as your potential ain’t that bad, I’ve got you covered.
Know your enemy
This is really the discriminator here in terms of good to poor revision technique. I’m so sick of people who think they’re boss and hardworking, when they’re just cramming every bit of information their eyes come across in the good old textbook. Textbooks are great (though I can think of a few exceptions) but the authors/editors like to add a little something something to engage your interest and whatnot, or they inadvertently look over a requirement for your exams, or your school doesn’t care enough to update your textbook in tandem with your syllabus.
So what your real best friend will be is your syllabus. Your teacher or the internet will give this to you. International exams will not be sneaky and test you on anything your syllabus doesn’t require. That being said, especially for the humanities subjects, the syllabus can be misleading. Take Economics. A skill like “Describe the causes of employment” may include jargon like cyclical unemployment and structural unemployment and god knows what else. But as long as you’ve checked off everything on there (for your year mind you, the syllabus varies quite year to year), find solace on the fact you’re well prepared.
Notes
I will forevermore be grateful to my teacher who introduced this to me. This is so, so important. Maybe by default you have some notes lying about. Those probably aren’t good enough.
Reading material will at most gain you understanding. However, when getting an A*, there’s almost an exact science to answering questions. Even for, let’s say, History. Any time you have to learn about an event, you need at least 5 detailed bullet points because the formulaic format of the papers require that. So really, your notes are a way to speculate questions and have pre-formed answers ready. Under each section of your syllabus, organize whatever content you have into headings and under each, have your bullet points. Being so detailed and thorough will mean a lot of content, so printing them out is recommended (I average 50 pages a subject). Have your headings in bold. Read through your page of notes, take the info in. Next, look only at the headings and try to recall what you’ve just read (not word for word, but at long as the points are there). A few days later, only look at the headings and whatever you don’t recall adequately, note down. At the end of your revision session for that subject, go back to what you failed recalling. Is it a bit like memorizing like a robot? Yeah, but these are exams and they are cruel and irrational. It’s all very good loving a subject and having great intuition, but if your blabbering isn’t fulfilling the mark scheme, tough.
Past papers
There’s no way your notes can be killer if you don’t consult past papers. Beware of content not in your syllabus, but you will eventually get a sense of how to answer things. Furthermore, you may get your bullet points for your notes directly from the mark scheme. These are good for pedantic mark schemes where though there a myriad of answers for the questions, only some are valid for the purpose of the exams. Definitions for your humanities may not explicitly be stated in your syllabus either, and yet there are only a limited number of terms they can test on you on. The definitions will be standardized, so just look it up. The way to do this is not go through every damn paper and copy down the mark schemes, but as you are doing your notes with help from the syllabus and textbook, cross-reference and supplement with mark schemes. Say you’ve extracted all the information your textbook has to say about GDP. Next, type into Google
“What is meant by GDP” xtremepapers (with the quotation marks). Or whatever your respective subject requires. For Economics, they always phrase definition questions with “What is meant”.
For subjects like Math (uh, probably only for Math), past papers are a resource for you to practise time management.
Time management
Speaking of which, there’s your revision timetable. Don’t do that gay thing where you note down
8pm to 8.30pm: Shower or
11.45 am-12.30pm: Math. So dumb. Firstly, there’s no putting such narrow thresholds. You’ll fall behind or have extra time here and there. What I suggest is, after you’ve done your notes for all subjects, dedicate a day to a subject. Do not do several subjects a day. It allows for poor depth knowledge and processing, and a convoluted mindset. Just set aside a day each where you go through your entire course. This will take 7 hours the first time. Breaks every 8 pages is good, of a 15 minute power nap or snack or exercise or those two episodes of EpicMealTime. It will be pretty mundane and tedious, but breaks will be your best friend and keep thinking of when it’s over. If you start at 9 am you can finish by 6 pm, and you’ll have a good 4 hours of whatever in the evening/night. After you’ve gone through all your subjects, if you’ve got enough study leave, go through them all over again. See how much information you’ve retained. As noted before, don’t read the notes this time. Just look at the heading and recall. You’ll probably (even after a week) recall 80% perfectly. It will also take about half the time to go through the whole course. Thereafter, the day before every actual exam, breeze through the night before and/or go over exam technique/criteria for marking (especially for things like source-based papers in History or Literature papers for English). Use weekends as opportunities for going through the courses coming up the next week. If you’ve ever go a good amount of time to kill, don’t go over revision again. If it’s the end of the day, just sleep on it. It’s pointless to do more. You’ve probably gotten the most out of what you’ve done, and any consolidating will be done when you’re unconscious and sleeping. Trying to recall random crap now will strain and frustrate you. You really have to sleep on it. The next morning, things will be crystal clear. True story. If it’s a whole day you’ve got to kill, don’t depress yourself. Take a damn break. More revision does not make for better retention. There’s a maximum capacity. Just go through it all once, and every few days or so again. It’s really not about quantity here, but quality. That’s why I do better studying the week before and getting A*s, whilst my classmates have been studying for months with their run of the mill revision and end up getting a B. I get the grades and the social life. Kinda.
Another thing, do start by 9 am tops. Your brain will get tired and dysfunctional when it hits 4 pm or so. And save the binge eating for sleepovers. Excess carbs will tempt you into hibernation. Just don’t.
