I am tearing my hair out with them!
I teach a core subject and they are seriously unmotivated no matter what I do 
I am trying to vary activities in lessons but all are met with apathy. For example, I found a video with some questions for them to answer while they watched last week - probably 3 out of the class actually tried the questions while watching. The rest just waited for answers.
Trialled short quizzes with a small chocolate prize to recap prior learning - most don't even attempt the questions, others cheating when peer marking so in the end it was abandoned.
Gave out practise exam questions for hw with the intention of going through them in class - 4/18 handed them in so I spent a free emailing/calling parents. I ended up with a total of 8/18 and most of those were very poor attempts, lots of blanks.
They are doing zero revision - I have provided video links, revision timetable, revision PowerPoints, websites, quizzes - matters not because they simply do not revise 
Massive pressure from above for results and I honestly don't know what else to do with them?! I am keepig records of what I am doing and who is/isn't engaging, contact with parents etc. But that won't get results.
I'm not well either with a bug - worked yesterday but was off ill today. Desperately need to go in tomorrow but still feel meh.
Anyone got any tips at all for motivator Y11? I've honestly never had such a lazy class. It's not just my class - others say the same but it's so draining!
