Hello,

You have computer science and english both subjects. If you are not studied well in 11th then you can face problems in basic things. Because in 11th class you know the basic things in or more than that and may be implied its in 12th class. So if you don't know the beginning then how you will go for next chapter. So I'll suggest you that you can revise your 11th class english and computer science as well you can study your 12th syllabus. Then it will be easy for you.

All the best.
