I didnt take Physics for my O levels and i'm very very afraid that it'd be a disadvantage for me.
quirke, there are a number of female pilots around. I know Jetstar Asia has a female captain (or two) and Air Asia has a few female pilots as well, so your gender is not an issue.
I'm not sure what the requirements are with CAAS in regards to having Physics before you can start training (I trained in Australia and have an Australian license), but the level of physics required to understand the concepts taught in CPL /ATPL theory subjects is at a very basic standard. I wouldn't worry too much about that at this stage.
Good luck in pursuing your dream to become a pilot. Where there's a will, there's always a way. PM me if you'd like some advice on career pathways. Mine was non-standard, but I got to where I am by purely persisting with the dream and never giving up.
