U shd say u're waiting for O level results, otherwise they might
think you're some sec 1 or 2 students, which is too young for most
jobs. Try to 'sell' yourself as in what u can do....e.g. your
skills, interests in IT/games, like to talk to ppl, learn things
fast, good with details (but must make sure they're true) - all
these will help them do a match for you.
