It sounds really hard for you, but I am sure you have thought of these: -how much S&L do you do in lessons? Remember not all work needs to be heads down writing, this helps re marking. -investigate interactive ways for 6th form to do exam prep- presentations, peer marked essays, not as a replacement for exam marking by you, but to mix it up a bit and take pressure off. -build in much more AFL into lessons by pupils -are you having to take on more responsibility?, it appears so, ask for a meeting with Lm to see if there is any one who can take on additional respn too, or if not if you can be removed from duties/dentention duty etc to balance the load -don't expect to give Ofsted perfect lessons everyday. -do you have a nice LA consultant? (know they are probably leaving next term) might be worth seeing if they can offer any support,revision lessons, take some meeting for you etc (if you have a good relationship with them and if they are very good) they might know teachers looking for a new job Feel for you, hope some of this helps.
