" one subject and take one exam locally"
You are only allowed 6 times in the exam room and there are fourteen subjects....
Suggest aiming to do them in 5 sessions, then you have a backup because you are also only allowed 4 tries at each subject.
Our grouping is as follows
Human Factor
Airframes
POF
Systems
Engines
Instruments
law
Ops
performance
M & B
Radio Nav
Comms
G nav
met
Flight Planning
Would suggest taking Instruments with Nav, though, because they share compasses and the INS, also performance and ops as they share stuff as well (hence the groupings above).
