Hello Aspirant ,

You should choose the second option , stay in Aakash and study with full dedication in your class 12 as you have more than one year now and it is enough if you study properly and regularly.

Aakash is a very good coaching institute and they will help you cover your class 11 syllabus also , just make sure you don't leave backlogs and complete your syllabus with Aakash , spend some time daily on your class 11 syllabus .For boards you only need 2-3 months and you can easily score 80+ percentage.

Hope this helps.
