In a school you would normally be given a couple of years to learn the following things, plus another year or two in high/secondary school after that (the idea being to give slow learners a chance to catch up). Many of you will not want to learn at such a slow pace, and you certainly don't want to stop learning for a couple of years, so you should take control of your own learning now and just get on with it yourself. Using the programs below you should be able to learn it all in a couple of months without a great deal of effort: five to ten minutes a day should be all it takes.

Keep returning to this page (and to the one for early primary maths) to do the tests again: you need to keep practising them until you get a mental age with a "+" written after it, and even after that you should keep going back to them every now and then to maintain your ability (at least once every year for the rest of your life).
