Standard Time to start coaching is 1.5 years before exam..so in one year classes comple and 6 months for fully focused self study...
Now your attempt due in Nov 14 so you shoud start any batch wich start classes from May 13 or july13 and complete your classes till may 14...then start self preparation....
During classes do regular revision of each topics which you study in classes otherwise after few months you will forgot everything and no use of classes..
All The Best
