=>practice make the man perfect
=>so practice and practice so you will definitely will become expert in maths
=> Doubts should be cleared immediately if you have any. But try not to disturb the class or the teacher while clarifying your doubts.
=>Vacation is a time to enjoy, really. But if you plan on improving your math, some changes are necessary.
=>Along with enjoyment, find some time (at least 2 hours) to review your previous lessons.
=>If you have any doubts, clear it immediately with the help of your elders or friends (you may also take the help of the Internet).
=>If you're done with your review, take a break for 1-2 days (don't be too happy, there is more to it).
