Quick grammar question...

[shifty_uk]

I've been writing a personal statement for uni. Just checking over it at the moment and I've noticed I often have words with capital letters - then a paragraph down I have the same word, but without a capital letter? That make sense?

For example:

The job was called Interactive

Then I'll write:

covering areas of interactive

Is this correct, or would I maintain capital letters throughout?

Didn't really want to post up the whole statement.

As I was giving the name of the course I studied, I wrote:

studied Multimedia Design and Development at

Later, as I was describing a job role I wrote:

My time there was spent heavily involved in front-end development

Would that be correct, or would I have a capital infront of Development?
