Prepare your child for the Olympics. I think that for such a task it is best to look for a student who recently won this Olympiad himself, or a teacher who prepares winners every year.

If you are not limited in budget, the best tutor is one of the compilers of the Olympiad. True, it is difficult to get to them: usually these are the busiest people, to whom a line of students stretches, and there are almost no such tutors online. In addition, a lot depends on the subject: in mathematics, for example, tutoring is possible, but in economics it is prohibited due to the draining of assignments in the past.
