IS kandB book is enough to pass the exam? i mean to say doing the mock exams that are freely available and thorough with book and concepts with good percentage(80).
The K&B book covers everything that you need to know for the exam; if you score well on everything in the book, then you can be confident that you're well prepared for the exam.
However, the free and non-free mock exams that are available are a valuable resource as well, ofcourse.
