im in o3 and have to give the exam of 7 other subjects in Oct/Nov 2020. I have Bio,Chem,Physics,English Literature,,Maths,English Language and Pak Studies to give currently however i was thinking of giving an extra subject privately. I have no knowledge of either commerce or business so please suggest which would be easier to start from scratch and can be done easily in 2/3 months without taking any tutions. I can get good notes/books and a little help from my seniors but i do not want to waste money on hiring a tutor. So, considering my circumstances, which subject should i take?
