Just wanted to pass on my thanks and recommendation to your books!
I've completed and passed all my CPL subjects in one go and now moving onto ATPL and IREX theory.
Roughly took me about 2 and a half months to go through them, and i couldn't have done it with your books, highly recommend them to anyone looking to go through their CPL theory. All exams were pretty straight forward, except meteorology which i dug more information out of the BoM book. Other than that, comfortable passes, so thank you very much!
That's another milestone passed. Congratulations - glad to here we were some help on your journey. All the best with the rest of your study and flying.
