This is an interesting idea, and one that we have talked about sometimes here at Brilliant Headquarters. We already have some functionality that lets you reproduce the desired outcomes, but letting students create a virtual "notebook" of their favorite problems might happen in the future.

Right now, you can use the Solutions tab on the home page to see your answer and solutions to problems you have tried previously. Alternatively, if you create a Shared Problem, it will be permanently stored to your Shared Problems tab, and you can revisit it there. This also allows you to challenge your friends with problems you have enjoyed, and introduce them to Brilliant!
