Another thought - at this stage I would be concentrating more on practicing the various types of questions / establishing your child's level/ identifying techniques for identifying the right answer / working on elimination techniques etc rather than focusing on how to complete the answer sheets - this is something for next summer. You have a long time ahead of you.
Yes I totally agree with Twinkle above. Definitely concentrate on the different question types and familiarisation with recognising these quickly. At this stage I found working through the Bond How to do Non Verbal extremely useful as a base, then moving onto the Bond books. I would start with the 10-11 yrs but by early summer I would move onto the 11-12 yrs. You may not feel this is necessary but my son was so used to the harder questions in the 11-12 books, he breezed through the non verbal. That said it was his strongest subject, but I would do the same again still.
Hope this is useful.
