Advertised a job as teacher of chemistry, then revealed at the end of the day that they could not guarantee I would teach GCSE or A Level chemistry but wanted me to commit to teaching A Level Physics. I was very disappointed by this. I was told they would make an effort to guarantee chemistry on my timetable and get in touch within 2 days - nearly two weeks later and I haven't heard anything. If you need a physics teacher then advertise for a physics teacher. Don't waste my time.
