for cpt; u can do by self study itself. ICAI books are enough; but are too erroneous.
You can buy extra ref. books for each subject. Try to finish syllabus 2 weeks before exam.
Then on, practise 3 papers each day; try to gauge ur SWOT.
U will be a rankholder for sure.
And in the day of exam; don't forget to pray to Lord Ganesha and Maa Saraswati.
