Goodbye Computer Science?

As most of you reading this will know, I was intending to take Computer Science for my A-Levels. Unfortunately, the only teacher who's qualified to teach us got pregnant, so the school can't provide the course this year.

This gives me a few options:

1. Where I'm timetabled for CompSci school will taxi me to a local college where they're doing the course. This will only work if their timetable doesn't clash with ours (and it's likely that it will), they actually accept us, and if they're doing the correct course.

2. I will instead take the ICT AS and A2 course this year, and then the AS and A2 CompSci course next year. Providing the school lets me. This would be quite good, because here's what I was previously intending to do:

Year 12: Physics AS, ICT AS, CompSci AS,  Maths AS
Year 13: Physics A2, ICT A2, CompSci A2

Instead, I'll be doing this: 

Year 12: Physics AS, ICT AS, ICT A2,  Maths AS
Year 13: Physics A2, CompSci AS, CompSci A2 

I'll still be doing all the courses I want to, just slightly differently.

3. I could pick a totally different option this year to replace the CompSci AS course and then drop it and take CompSci at AS or A2 next year (small problem; I think taking an A2 requires having an AS).

As you can tell, I'm in a bit of a pickle here.

My current situation.
