After all that you should be able to simulate the exams and get >80% results. This is how I study for the ATPL theory.
I would also agree with this approach. Whenever you have completed a larger chapter, hit the QB and don't worry if you're not getting over 75%. Read the explanation and you will learn a lot. Flag the questions you did wrong and redo them once you've finished a particular block of questions.
Aviation Exam lets you work on specific sub-chapters within each topic whereas BGS only divides each subject into larger topics. That's why I mostly rely on Avex, if I have spare time I work on BGS to practice for the school exam.
