ATPL Online and BGS Online - what's the difference?
So, I was looking for a question bank and I know that one of the most loved QB is Bristol's QB.
It turned out that Bristol GS has both ATPL Online and BGS Online as question bank.
So, what's the difference?
Which one is the best as of now?
And how do you compare Aviation Exam to these two? (I gave a look at their demo and liked the explanations).
