Hello Student,

First of all you must should mention about which examination marks you are talking about . If this is all about your school examination marks you must should go to the school authority for the respective teacher to get clarity about that. But as you have mentioned that total marks is 7:20 I can guess that you are talking about Neet examination. Basically in NEET examination if you got 25.5 percentile in physics, 46 . 40 percentile in chemistry and 20.7 9 percentile in biology . That actually don't means the marks are those . Basically in any examination percentile means some different things like as you get approx 46 percentile in chemistry that means there are total 46% of who scored less than you in chemistry . That actually doesn't mean that you get 46 marks in chemistry. When all the percentile are got calculated there can be some difference . You got average 22.33 percentage that means there are that much percent of people who scored less than you in aggregate. Hope you understand that well.
