i have done 2 years of iitjee coaching in mumbai but i have messed up many of the entrance exams so i dont know what to do now....but the thing is that i am determined to study really hard for another year but im not sure if i will make it to iit or not....so what should i do??? because i know that i can work really hard to my best potential-which i did not  do for the last 2 years.....my 12th results are not out as yet but i got a 90% aggregate in my 10th in PCMB......and my parents dont want me to drop a year.....

i am very confused...please help...
