Welcome to the forum jbsmum
There's lots of helpful people here, ready to answer questions but also a good way to learn is to go through the Stickies at the top of the different forum sections and to also read through old posts, that may be of interest/relevance.
People vary in their approach here; DIYing or tutoring or perhaps some of both.
The online practise CD's/papers are good. Giving practise in specific areas in all 4 disciplines for RGS, to help strengthen these areas, and also they have full practise papers. There is a vocab builder CD, and many books for vocab building help. Playing word games such as scrabble at home, and lots of reading also helps improve this area.
You will also find many 'How to' Technique books, which are great for any parent going the DIY route.
