actually depends on you,if you can excel in 1 year,then you can take next year lo,between your sister already sit the exam already right,that means she already learn the subject and now she only need to revise the subject,even if you register early this year,she can sit this year exam.
i think the 2 year gap is for the first time exam cause whoever wish to sit the stpm exam after spm,they need to wait for 2 years.
between remember,next year will be the last exam for the current system and syllabus,after 2012,stpm will change to modulus system,the syllabus also will change,so better hurry,the registration will open from january to march,after next year,i also dunno how private candidate want to take stpm.
sorry for my poor english.
