My brother's Mid sem result..

My brother is in class 12th and taking JEE coaching from this year but his midsem marks are dwindling at a very fast pace. Don't know if he will be able to pass class 12th, Teachers are suggesting ki jee ki coaching hatva kar cbse ki rakh lo but the funny part is that he is already enrolled in a cbse coaching in the same institute from where he is taking JEE coaching. Jab pucho ki aise marks kyu as rahe hai toh kehta hai ki cbse samjh nahi aa rahi par jee ke questions solve ho rahe hai par uske mocks bhi abhi shuru nahi hu aye toh we are taking his word for it. But I am from commerce background toh mujhe jyaada pta nahi ki kya karu raat bhar jga toh rehta hai par pta nahi marks kyu nahi aarahe kuch kaho toh frustration nikalta hai teachers bahut worried hai kyuki class mein woh bilkul chup behta rehta hai without any friends. What should I do yaar..... JEE YA CLASS 12TH???!
