IPS, the Tutors, Bright Sparks (Susan Daughtrey) and Walsh papers are all suitable. Make sure you choose the multiple choice ones. You are running rather short of time - perhaps your best bet would be to download the Tutors full length papers from this site? You can order papers from here too and I know from experience that they arrive very quickly but every day counts at this stage!
Don't wish to be rude - but you do know the test date is earlier this year, don't you?
Sounds as though your DD is doing very well. The short Tutors papers (E papers on this site) are good for encouraging DC to speed up.
