We actually have a resource that was created specifically for the purpose you described! It's called the Official Guide Study Tracker, and you can access it via your Student Center!
You'll want to go to your class resources page in your student center on our website, then click on the subheading (in gray) called "Course Downloads." Once there, you can download the official guide study tracker.
You'll see there are two different trackers. One is to keep track of which Official Guide problems you've completed, the other is to keep track of the overall work you've done for the course. I'm sure you will find both useful (and both come with instructions!)
If you have any questions on how to use these two resources, please let me know! You can also call us directly at 1-800-576-4628 or email us at studentservices[AT]manhattangmat[dot]com.
Best of luck with your studies,
