I'm interested in targeting some of the South London grammar's & comps with streaming sets. Everything I've read suggests I need a tutor. I've been in touch with a few I found but the regimes are intense. 2.5 hours a week plus 3 hours homework for 2 years & things like if you don't do the homework or pass the assessment you can't continue etc. Is that normal? My dc do quite a few extracurriculars & I don't really want them having to give everything up. Or is the reality that if I want those schools I need to do this?
