my thoughts on cpaexamhelp -

i used this in conjunction with cpareviewforfree and gleim to finally pass the exam.  it was very helpful for BEC (especially since it was free).  they had good explanation for answers.  However, i also purchased FAR through cpaexamhelp and it didn't come with any explanations, you can challenge question answers but you don't get a response from anyone to say that the challenge is being reviewed.  I was able to at least use cpaexamhelp's FAR final exams to practice for the real exam since you don't know the answers to the real exam until it's graded.  They have realistic final exams which can give you the practice you need to pass the exam.  I would highly recommend getting the BEC section but only get the others if you already have a strong basis in the subjects and are only intend to use it for practice final examinations.
