Yeah, I did an evening one for my first as well, it was ideal. From the ones I've been in and watched, the novice group in the evening is way more novicey than the novice group on the full days is, you get more clowns in the wrong group at weekends. But the evening was a great intro to trackdays. Short sessions too, which would annoy me on a full day but it's quite good when you're just getting into it. Though that might have changed of course.
I'd be back in novice anyway, I'd do intermediate I suppose if there was an inters session but I'm definately not advanced
and I won't be pulling out the stops either, if I do this one it'll be a bit more relaxed.
