Not a very exciting present but make sure you have a copy of MS Excel.
I used the Bristol online database as a revision tool for my ATPL exams, an absolute must. I used Excel and listed all the questions I got wrong. Using a simple formula it would highlight questions I got wrong twice and scream at me if I got a question wrong 3 times. You can copy the list of question numbers you got wrong into the database and do tests with just those questiuons. Towards the end you don't want to waste time with questions you've been getting right for months.
Alternatively get them to buy you something real nice like a GPS or a holiday that you only get your hands on once the exams are done.
