Hi javed!! Hope you are doing well!! CLAT is an important exam if you want to get in good law colleges of our country. It includes many subjects like logical reasoning,English, current affairs etc. I would say, subjects like logical reasoning or english, you can practice in 10 days and get a grip on their problems, but current affairs and GK needs to be studied on a regular basis to get a good result. It can't be studied in a short period of time. But is your current affairs is good, then you don't need tk worry, study well in these 10 days, give all your effort and solve as many probelms as you can. You will surely get a good result.
