Oh yes, I didn't use the HF Thom book either. I found the dark blue one, with the yellow diagram of humans on the front (

can't remember the author) good, but then I'm a biologist so it was all revision for me rather than new information...
I didn't use the confuser, but still managed to get >90% in all the exams. Except a/c tech, which I sat having not even opened the book, and still scraped a pass. I
did then go back and study properly and resit.

The tests at the end of each chapter in the Thom books are much harder than the ones you'll get in the real exams, but are very good at checking just how much you've learned. No cheating!
You'll find that as your lessons progress you pick up a
lot of information without noticing. And you'll learn a lot from reading this forum of course.
Thanks BRL, the cheque cleared this morning.
