Tutors have lives too, you know. Maybe she has other commitments. It does happen sometimes! She's a teacher; she has lessons to plan, homework to mark etc. She'll have loads of other references to do too. And then she's allowed a life outside of college and probably has a partner and kids which need attention.
If you hadn't completed some work, would you like being nagged constantly? No, you'd come on here and moan that it's unfair. But because it's you that wants something, you want it doing instantly. That's not right.
If I was your teacher, I'd deliberately do it slower if you annoyed me. And maddi, they can give a bad reference if they feel it's justified. So don't piss them off.
You'd also be on here moaning if she stopped teaching you or marking your homework because she was spending her time writing references all day. But checking UCAS applications is an awful lot of work, and imagine having to write 30 difference personal statements. Because that's what it's like for your tutor. She'll have to write a reference for all of you, and make sure it's good. And some students will change their course choice really late and expect the tutor to write a new one. And some will expect her to fit in loads of stuff from outside of school at short notice. And some will want their predicted grades changing, or their subjects, or "can you write a bit more about my AS grades, please, miss?"
So to come on here complaining is very selfish of you. And it's really stupid to do it when you've got your college in your profile, even if it is spelt wrong. "Matthew" has 2 T's.
