I am currently 3-4 months away from my CAIE AS-Level papers. I will be appearing for 4 subjects Physics, Chemistry, Maths and Computer Science.To start this, I have completed the Chemistry and Maths syllabus, and approaching near end of my Physics syllabus. After this I will be focusing with full pace on Computer Science(which I have had completed 35-40% of the syllabus). Keeping in mind I have already started Past paper practise of Maths, and Physics. Is it still possible for me to get Aβs in all these subjects?
