what is total marks of her examination? how top student of jee mains are selected for advance? will we get admission on basis on jee in government college and what will be their cut offs?

I didn't get the first question which you asked. What's her examination? Correct the statement to know the answer. Talking about your other two questions, firstly, cbse releases a cut-off list after the declaration of result which has a cut-off list for each and every category. If you secure marks above than the cutoff then you will be allowed to give the jee advanced. After jee advanced, every college under JOSAA ask you to submit preference if you either clear jee advanced or mains. Depending on your score they will allocate college
