It Depends upon your hard work & Consistency, as the course is very lengthy so, it takes times to meet with all expectation.

Still you can do it by putting extra efforts.

In my Opinion you should try to appear after preparing 6 Months REGULARLY.

InSha-Allah you will achieve your goal!

Good Luck..
