My CBT expires in September, and as I'm starting a new job on Monday, I won't have time to go for my license for the next three months at least (probation period). What do I need to do to keep it, if it's even possible? It's not really that critical, I'll fork out again if I need to but I'd rather save the cash and use it for lessons. I can book my theory fairly soon, then I just need the first MOD to prolong it don't I?
