I am a student of FIITJEE now in 11th std. In the eight weekly tests that we have had so far, I mostly ranked within 10 (out of 500 students). But in the last 2-3 tests, my rank has been slipping - because I lose about 20-40 marks due to 'silly mistakes'. The types of mistakes I make are:

- not reading the question properly and missing out on important information
- replacing + with - signs especially in equations
- missing a few numbers while calculating (e.g., missing a denominator)
- calculation errors (such as 3^2 = 6)

After each test I analyze my mistakes. I am very concerned that I should not repeat my mistakes. But the problem has not decreased - it has in fact increased over the last 2-3 tests.

Kindly advise on what I need to do to increase accuracy?

I have tried setting a time limit while solving problems at home. But the time is never enough (because the concepts and problems are new). For example, yesterday evening, I wanted to solve 10 problems and set a time limit of 30 mins. But at the end of 30 mins, I could only solve 4 problems!

What should I do?

Please help. Thank you in advance.
