18 is a very very sensitive period

even more so becoz it's your last yr of highschool

it's normal for them to worri
especially u're at aust by yourself (are u???)
is the guy in aust or in hk???

the thing is you're not trying to BEAT your parents
by having good grades while u had a bf
grades are all for yourself
i und. one girl oversea and really want to have someone that would listen and takes care of you
(i'm pretty sure that your parents would have guessed anyway)

as the other bro said
wait til all grades are in and acceptance cin tell lor
nth to lose

although
a relationship that is exposed is alot more comfortable and the joy of sharing with your loving family abt having a GOOD bf, is priceless

good luck with that
and wish you well on school work
