Dear Saroopya, 

If you have answered the question and clicked on the Marked for Review, then also it will considered for evaluation. 

And if it is a bonus question, then also you will get bonus marks. 

Therefore do not worry .If you have anwered it,then surely you will get your marks. 

And if you have only Marked for Review and not answered it, then it will be not considered for evaluation. 

HOPE IT HELPS.
