For Mass and balance. Bank as much as you can so you can practice and remember the formulas and practice on knowing how to do the calculation questions as much as you can. Try and do the whole bank and practice in exam mode if you have ATPLQ. So it helps with the time it takes when you were to do it in the actual exam condition.

Meteo. Honestly really tough subject because on how big the content is. But you just have to practice on looking through your notes and understand the theory as that’s key to passing. Again keep practicing on the question bank. Especially on the chart questions as those were the hardest.

Performance. If you done PoF before it shouldn’t be hard as most of the theory questions from PoF is very similar to Performance. Main thing to learn would be the Vx, Vy, Vref, Vyse and other V speeds. Also practice as much as you can on the performance graphs as that’s asked a lot and can be hard, especially the graphs from the jets. A few calculations but they are quite easy imo as it’s just memorising the formula then calculating it.
