If my student gets a rank 100 and other students get rank 105 ranks are similar and you can take back the fees. I get nothing.
If my student gets a rank 1000 and other students get rank 1050, ranks are similar and you can take back the fees. I get nothing.
 If my student gets a rank 300000 and other students get rank 310000, ranks are similar and you can take back the fees. I get nothing.
