Has anyone here done Key Skills qualifications?

Now I'm at college I have to do Key Skills in addition to everything else. I'm currently doing Communications, but other units include Number and IT. So far, I've had to do a leaflet, and later I'll have to do a presentation and a discussion about something.

Due to my bad GCSE English grade, I had to start on Level 1, but level 2 and 3 do seem a bit hard (I might be alright doing level 2).

I think it is a bit pointless haveing to do Key Skills, when the course which I am doing has it's own communications and maths unit (the teacher says the maths is about the same as AS Level). And I already have good grades in GCSE Maths and ICT.
