Of course , but we all do that and we don't all have a certificate for it . This does not mean you would manage your fuel better than the next guy or you manage anything better than the next guy . I can't help but feel that this is all just so you can look good at the QF interview . and with the pilot shortage on its way and the attitude you have mate i doubt you will have any dramas . see how you feel chris after 15 exams ( CPL , ATPLs and IREX and see how much you wanna study) .
All the best either way chris .
cheers
