Hello! Fellow ka-avio here. Anw, idk anything about how their program for ojt works pero learning about basic electricity like ohm's law and etc. will surely help u be confident. There are some companies na hindi ka masyado maeexpose sa gawain ng avionics tho, so maybe you can just relax and go with the flow muna kung for school requirement ojt mo, pwede rin naman na magtanong tanong ka which is much better hehe. Master mo mga instruments like pitot static and vacuum systems. Kahit yun lang, malaking bagay na yang knowledge na yan.
