Hey falguni,

I don't think so to do nursing in diploma on the basis of 10th. You have to work hard for 12th gseb in chemistry. If you think in pandemic time is wasting for not doing anything. Keep doing some productive work,keep running if you want to survive.

If you have given your two years for 11th and 12th make it worthful. Its only one backlog wait for right time to do well, work hard and be ready for chemistry go through the syllabus and keep studying daily,you will definitely get results and then explore everything.

Go through it
