Residential Tutoring - Maths

[TGCOTF-dewey]

Afternoon Folks, given so many of us are parents of exam aged kids, I was wondering if anyone had any recent recommendations for A-Level maths residentials - ideally one week. For the sake of a few grand, it's worth the investment if it boosts his grade next year. He wants to take Economics if that makes any difference to recommendations. He could do with any boost as the points requirements are spicey compared to my Uni days in the 90s.

Online reviews are often mixed, so personal recommendations are always good.

Thanks!
