A guy i spoke 2 when i was doing my ppl was in the process of finishing his cpl and said that after he'd finished the material he did the qb again and again for a month or so and by the time he sat the exams he knew most of the answers before he'd even finished reading the questions. i think thats wot ill be doing when the time comes 2 sit exams, altho obviously with planning and nav etc u cant really do that as you could with say HPL
