I just took the new Meteorology exam and it was very hard.
My usual method is to read Pratt's book once, then again, then the oxford CBT, then do the confusers once, then again with the wrong answers and then finally the Oxford CBT answers. So probably about 20 hours in total.. I want to learn the subject rather than the questions.
This has stood me well so far, the 4 old papers I did it was high 90's. The new paper today was very hard and there were 3 questions which were 50/ 50 and I got lucky on. I got 85% in total, but it could have easily been 70%
Having a break now...
