once you have done the Peter Robson books 1,2, move to Schofield and Sims progress papers. They are good solid exercise with questions clustered by topic, so you can easily see the weak areas to target.
Once the fundamentals are clear, move to Heinemann word problems book5 to improve speed.
For English start with First aid in English for solid basics in grammar and punctuation.
For any weak areas that I was not clear on,
www.primaryresources.co.uk, has enough explanation, ppts and simple exercises to start with.
Hope that helps. We used CGP, bond just to check the improvement in scores and mock tests, not core prep.
