Oh how sweet my kumiko is.

Well, u can always start engaging with co-cu activities. It's not as bad as u think it is. True, it's indeed tiring but profitable (in terms of marks and experience). It's ok to just get involved in the co-cu and not hold any important positions. being a normal member would be ok but please do engage with the activities like camps or charity works. Ur involvement in such activities will help u much in boosting ur co-cu marks. And if u just attend the clubs meetings for once or twice but u get involve in their activities at national level, u can ignore attending the rest of the club meetings as ur attendance will be counted full.

I was once one lazy ass for thise kind of craps. But trust me, it's exciting after u get into it. Back when i was in form 4 and form 5, i went to national camps alot, and i got to make friends. It's seriously exciting to meet new friends and 'makan angin' at the same time. 

I told you i am not your kumiko!!!           

Form 4 and form 5 active, then it's enough for co-curriculum.
