Hi everyone!
I recently gave a GMAT mock w no prep at all and got a 345, I'm thinking of giving the GMAT in December/ January and wanted prep advice.

1. What are the best sources considering I don't want to join any coaching institution, like TTP, Magoosh etc.

2. I bought the OG GMAT 2025-26 books, and found the questions way too easy compared to the questions in the mock or the GMAT Club questions, what do I do?

3. I am willing to devote 250+ hours for my prep, (ik the base score is bad), but i don't wish to waste my time w the wrong material/ methods.

Please help.
