My name is sunil thakur and I am currently studying in a CBSE school .I am using this this app quite a while ago and it helps me lot in revising notes when I am outside .Their are previous year question paper which you can solve for practice .It is very useful for students as well as parents and teachers.I am preparing for JEE so it helps me a lot as it contains previous year question papers too with solution.It may require some improvement in the area of content eitherwise In my opinion it is must recommended app for students.
