17F got cooked by FIITJEE

One of my friend got toppers batch from her FIITJEE admission test. She performed good by unfair means, She had the question paper and answer key. She got it from her friend who had some family connections there. She got a good scholarship and will be getting toppers batch. But in reality she is just average in PCM. She knows she can't make with pace of the toppers batch. She know she has made a blunder as her scores will decline as soon as she joins classes. How to correct this
