Hi,

English and mathematics are the two subjects which are most horrible for many students. Preparing for English and mathematics is not so difficult.

For English subject the first and foremost thing important is your reading skill. So improve your reading skills then focus on vocabulary and grammar. That's it. These will improve your english.

For mathematics understanding the problems and then solving them on your own is the best way to prepare. Practicing the problems helps in increasing your ability to solve them.

If you find difficulty on preparing on your own you can take guidance of any good teacher you know.

Hope you find this helpful.
