Hey,nobody should say JAMB's an excuse for not being in school bcos der r too many smooth n easy ways stroll in2 our 2day's Nigerian university.
Sit down n talk 2 urself:Go get a DIPLOMA or PRE-DEGREE form,its just 2 years tops and u r good 2 go.Infact by now u 4 dey yr2 or yr3.
Anyway my friend good luck.
