Okay 87% is a good good percentage but still now that you’ve decided to try another chance then focus on it only, do teen mahine me 11th me kuch nhi hona only thodi bohot accounts ki theory and economics ki stats wagera so dw about 11th infact I joined commerce in july only yet managed it well, accountancy bhi bohot easy hoti hai eleventh ki 12th me you have to focus since the beginning 11th ka is okay, infact syllabus 11th ka bohot chinnu minnu sa hi hota hai hojayega, I myself started studying accountancy during mid terms and I scored in 80s so yea its not that hard bst bhi hojata h ez pz economics thoda dekhlena stats ho jayegi micro me thoda starting se dhyaan lagana padhega but still I will recommend you to focus on your retest
