Just passed the Meteorolgy exam in the first week in January - 78%.
I used the Oxford DVD and a good few weeks on the Bristol Question Bank. The DVD gives you the overview / understanding and the Question Bank gives you the exam practice. It can be a slippery customer this exam, I felt confident going in and had devoted the majority of my time to General Navigation which I was sitting at the same time... and then only scraped a pass!
The problem is that you have 90 individual questions of which the majority are one mark. You need a good overall understanding - perhaps more than other subjects to be able to cuff your way through. You have 90
individual chances of being tripped up.
