You could also write about:

What you want to get out of this course.
What your aspirations are i.e. to become a midwife because....
Why you feel you need to gain the skills you will at college
What you have heard about the college locally (helps to visit their website and see if they have any awards you can mention...they like that!!)
Why you chose them not another college
A little history about yourself....I told them that I needed to do this now at my time of life because I had put everything on hold for everyone else but now I was able to concentrate 100% on achieving my goal...blah blah etc etc...lol

70 Words is not a huge amount....they just want to see you can actually put your thoughts into writing that makes sense.....

Good luck! You will love it! x.
