That's good news!
It's been a few months since your course ended, so you've likely forgotten at least some of the information. You may want to think about re-taking the course (you get a
big discount if you want to do this - ask the office if you're interested:
studentservices@manhattangmat.com). That will give you a set schedule to follow, as well as access to instructors (during class and office hours) to ask lots of questions.
For the material that you still remember, you can push yourself to a higher level of understanding (concentrating on harder problems, for example), and for the material that you've forgotten, the course and curriculum will be a good refresher.
Since you took the course, new versions of the OG Quant and Verbal supplements have been published. There are only about 75 new questions in each book, so it's up to you whether you want to use your older books or the new ones.
Talk to the office about how the re-take works and see whether you think that would be a good option for you.
