Wow, amazing advice. Thank you. At the moment DD is working with a tutor who is setting her Bond papers. I am beginning to worry about this approach now.
I agree that those targeting North London Consortium schools need to move beyond Bond to do well. However, if your DD is getting between 65% - 80% on Bond maths practice papers, then there may still be some fundamental topics that she is yet to grasp fully. I would suggest investigating whether she is consistently getting certain types of questions wrong and fixing those first (IMO, Bond is helpful for building fundamental knowledge).
Last year, my DD (who is now in Y6) used Bond until mid to late April, at which time she switched to Schofield & Sims mental maths and started practicing with prior-year indie exams (including those from the North London Consortium).
