Well shahana move forward,join C.A. ,u can do it,start with basic as already suggested 11th & 12th books from good teachers,u will find it interesting,however it will take some time to get used to this.It's a wonderful course.
There is no need to come from basic, because ACCOUNTS is only one subject, rest all r different from 11 and 12th. so get proper couching for accounts alone.
The only probelm is u have to work in a audtior office for three and half years. If u can mange that u can get in for sure.
