My DS had a tutor and he worked through the Bond books for English, Maths and V.R. 9-10 and then 10-11. He also did 10-11 plus (Bond). I also bought him the 10 minute test Bond books for Maths and V.R. which he enjoyed doing as a little extra in the last month. They literally do only take 10 minutes and they managed to keep his speed up whilst also revisiting all of the V.R. techniques.
His tutor supplied the CSSE papers and he didn't start doing these until 4 months before the test. Hope this helps and good luck.
Yes I think upto 10-11 would suffice for now. The 11-12 bonds were extremely hard for English - but not so bad for VR and Maths. Also, talking of 10 minute tests - the IPS series do some really great daily 10 minute tests. I am just clearing up and storing away all the papers and books we accumulated over the last few months. What a journey my son and I have been through- it's nice to have a nice clear desk back!!!
