Himanshu, take a deep look at what you are doing and what you would like to do. If that is different then move towards what you prefer to do with full heart and confidence. You have to get then focus back into your study and this is not easy till you like what you do. Wish you the best for your care

Hi dear you should not worry about work hard with determination and you can surely clear your bsc 1 st year.
