So my 9 year old has failed swimmer 2 about 3 or 4 times now. Here's the issue. We go milton swimming classes at the various community centers across milton (leisure center, sport center etc). The problem is believe (and I might be wrong) is that there is only one class per week. Hes gone to both group and private lessons so far. But I think its a lack of practice.

How can I get him more practice? I dont have a pool at home and honestly dont really have time to do it personally but j wouldn't mind him going 2 or 3 times a week to get better at this
