Get stuck in. It might be a an incentive to do well at your exams if you have your career in bag and a BRNC start date in your diary..... If you start the learning now you'll know it all in no time at all. Doesn't take much; better than piling it up until the last minute having neglected to learn about ships because you were too busy revising. At least if AIB is out of the way you can really put your all into your exam revision.
