How to improve my scores in coding tests like hacketon, hackerrank, skillrack etc?

Answer 1

Last I checked, HackerRank's...

Scores are based on how many of a challenge's test cases you pass.
* If you want higher scores, pass more test cases.

Placement within a scoring level (like those who got 100% right) is based on the time since the challenge was posted.
* I don't believe HR makes an allowance for time zones; getting high rankings means both correct and fast.
