A very good question. The internet is full of people who will tell you to ignore the course material, ignore the revision weeks, its all about hammering the question banks. Certainly that has been true for many people when the exams were stable but, when they are not so stable, not so much, as entire courses of students at certain ATOs have discovered recently. I'll leave it to others to comment on the value or not of a sound basis in ATPL TK for future career and interviews, doubtless there are many opinions! ASG are good people.
