For a student who got 90 percentage in plus one kerala syllabus. Did he need to improve???
Dear Student,
You have already a good score of 90% . And obviously it is 11th class score. So you need not to improve it. It has no effect on your further studies. You just have to focus on your next class that is 12th. Everywhere 12th marks matters not 11th. So just focus on 12th class studies and do better in them.
Hope this helps.
