Hi SuperPilot,
The number of questions in each exam, as a general rule of thumb:
75 - Aviation Law
76 - Aircraft General Knowledge
56 - Instrumentation
22 - Mass and Balance
34 - Performance
56 - Flight Planning
47 - Human Performance
90 - Meteorology
54 - General Navigation
59 - Radio Navigation
50 - Operational Procedures
44 - Principles of Flight
23 - VFR Communications
23 - IFR Communications
However this doesn't mean the number of questions will equal the number of allocated marks. The more difficult questions are weighted with 2 marks or as in the case in the August Meteorology exam 3 marks (one of the last few questions).
Each exam has to be passed with at least 75% of the allocated marks.
Learning the subjects by use of feedback and past papers will not guarantee you a pass. You have to learn and understand the theory behind each subject as well as going through the past questions. The real question bank is updated all the time with new questions replacing older questions.
Although these are multiple choice questions, they are not easy. The questions are designed to enable the exam to ensure one has studied the required material and not just gone through feedback questions.
Best wishes,
Charlie Zulu
