Summer revision/tutoring camps/courses for pretest ISEB 11+ Recommendations please

[Idomybest]

What summer course would you recommend? How did your child find it helpful? What difference did it make? TIA

I do not want private messages from the tutors/groups themselves.

I think you'd be better off buying a set of books/tests and going from there.

How old is your child?

9 - will be 10 soon, sitting pretest in November 2019. We have the books, but wanted some practice on the computer - a simulation of sorts before the actual exams.
