That's exactly it. More questions for practice. The order is not really relevant, but the earlier questions are easier than later ones.
Yep.

OG 12 is a must buy . The supplements available are for extra practice . Each book has question in increasing order of diificulty categorised as EASY , MEDIUM and HARD. Attaching BTG OG 12 error log. If you are worried about the order of books to follow then first go through the OG12 then other books , anyways all are official questions so it really wnt matter with the order as far as you cover all :) .

Happy Learning .

The supplemental guides is mostly problems that were taken out of the OG11 when it was updated to the OG12 - there are extra practice problems but it does not contain many difficult problems at all. I don't recommend them unless you have used the entire OG becuase the trick is not to do more problems but to learn more from each of the problems you do.
