Simple! I can give you several strategies.
1. You can start by disappearing often and eventually completely
disappear.Hopefully nobody notice you.
2. You can say that your last semester result is horrible and
you cannot handle between CCA and school. My parents and form
teachers are advising me to let go of my CCA.
3. You can get tution on the same day that crash with your CCA
days.
4. You can say that your family is very poor, so you need to
work every evening till 12 am at mcdonald.
As long as you show your academic results (report book) and
convince that your CCA teacher what you are failing!!! 99.99% your
CCA teacher will have to let you go.
1. haha can't cos there's only 10 ppl in one squad, quite a
number left the cca.
2.haha also can't cos i'm not doing bad in academic, in fact i'm
doing quite good.
3.haha also can't cos the "sir" will ask you whether can change
it or whatever then call parent
4.no one believes though
