Not true. I used Becker and only Becker and it more than prepared me (a score in the high 80's).
I haven't used any other courses, but generally passing scores come from people who study enough. I give a lot of credit to Becker for their format and streamlining the material but think I could have passed with any of the other big review courses (Becker, Wiley and/or Roger).
I'd be nervous to go with a ‘smaller' review course (like Yaeger, Gleim or CPAexcel — although I'm sure they all have their champions).
& Ninja Notes are NOT a review course – just a supplement.
