a small but potentially annoying and costly one
I studied for ppl tech. exams 13 yrs ago so it may be different now,but I doubt it. Remember that a pass for each exam is only current for 6 months. Bad weather and tech a/c etc can conspire to increase the time required to reach the GFT test. So try to time your theory exams carefully as there is usually a charge for marking the exam apart from the sheer ballache of taking them repeatedly. It is not a good idea to get them over with asap, but early study for them is certainly a good thing and besides, its all very interesting.
