Guidance

Hey, I gave THE OG GMAT in 2023, right after college. I scored 680 in that and wasn’t satisfied as I screwed up in quants. I wanted to give it again but a week later I started my first job and then well life happened. Now I have a couple of years of experience, I want to give GMAT again. So would be great if someone could guide me what is GMAT Focus and how it is different from the OG, how much more I need to prep for considering I have a solid base, and where could I get a good course from that isn’t very lengthy.
