I'm in year 11 and transferred from foundation triple science gcse (AQA) to higher combined IGCSE (CIE)
do you think its possible to go from 4-5s to 7s+? I'm currently using Seneca, century, quizlet and my own notes for revision, aiming for 30mins - 1hour of each science per day
You can 100% improve your grades.But you'll most likely have to put in more time. Especially in the months coming up to the test you'll need about 3hrs a day. You're resources are ok but try blurting, flashcards(Anki) and the Physics and maths tutor flashcards (saves the time of writing them urself). Past papers and exam style questions are also essential.
