Hi abhijeetsinghai,

If you purchase the Reading Comprehension guide, you will gain access to all 6 CAT exams and the Reading Comprehension Question bank (25 questions) for one year from the day you register your book. To gain access to your online resources, you need to follow the instructions on page 7 of the book, which involve entering in a 32-digit serial code located on the back inside cover.

Hope this helps!
