C1 Linkers

It isn't worth phoning Jofhn, seeing that/so that he's arriving in five minutes

Even though/despite she's working really hard, I don't think she'll be able to catch up

He gets a good salary though/since the job itself is quite monotonous

Could we arrange my timetable so that/in case I don't have so many classes on Mondays?

We can't afford to have a holiday this year as/yet we've got an overdraft at the bank.
