At this satge...
As you say you have done alot of ground work, perhaps start a few short tests from the IPS range [you can keep the res of the pack and use as part of your weekly regime]
Then get onto the 80 question tests, perhaps the first 6 of The Tutors followed by 8 from Bright Sparks and lastly the NFER,[ when testing NFER ensure HIKNOS is practiced along with all other types in your weekly sessions, and you cross off the last 5 questions]
I would keep your weekly time table to..
1] A test
2] 30/60 MINUTES, Dipping into various types, do not just cover types your child finds hard, keep on with ALL 21 [ could use the rest of the IPS tests, Walsh or the tutors last 6 ]
3] Vocab work, reading out loud, flash card games [put cards up round the house. Vocab is without a doubt the BIGGEST problem.]
No need to be scared! Its practice, practice, practice.
