'tis a small world indeed
I did Level 1 at Farnborough Tech last year, which finished at the start of June. Since Level 2 doesn't start until mid-September, I looked around for other options & saw 4 evenings in July at City Lit advertised as a 'Level 1 Revision' course. Ideal I thought & signed up. In practice it was more a continuation of Chika-san's existing course, but that wasn't really a problem. I think I knew more vocab and grammar, but had very little speaking practice, so the lessons were really good for me. I think Chika-sans students were a bit more fluent in hiragana then me, but my katakana was better.
However I have signed up for the Farnborough classes in the autumn, because it's difficult for me to get to the London ones on time (and it's a late night by the time I get back so I'm knackered the next day). It would also cost a lot in train fares. However if enough people don't sign up for the Farnborough classes, then it's London bound again!
