Grades are just things that are tested, not everything you want/need to know/learn.
But they are cumulative. So say you decided that the first exam you will take will be grade 3. That doesn't mean you can just pick some G3 pieces and go for it - to pass a G3 exam, you will need to have the same skills as someone who took G1 and G2. The difference is, you don't take the exams for G1 and G2. It might take the both of you the same time to get to G3 standard - by skipping grade exams, you are skipping the exam, not the learning!
You can take any exam you like, and skip any you like (indeed, you don't have to take any, ever; except in certain circimstances, e.g. if you want to do a diploma you will need a grade 8).
yes thank you now I understand hehe =)
