Application letter

Well I'm applying for the position of secretary in one of the organizations at my school. But every draft feels like I'm just praising myself and I think it's making me seem very self absorbed. I wanted to know how to write a good application letter

You've posted your question in the 'Ask Student Finance England' subforum which has caused the confusion.
I've moved it to a more relevant section where you'll hopefully get some advice.

I had an employees apply for a position that would be a promotion for him. Part of the interview was a 5-minute speech on what he had done in his current job. I agreed to hear the speech and at the end of it said, "You've told me what has been in this department, but not what you did. Go away and put 'I organised' or 'I introduced' at the start of every sentence." He rewrote the speech and got the job.
Long story short, a job application is no place to be modest. Sell yourself! Job spec says 'we need this', you say 'I can offer that because...'.

I get it, but what if you have no previous work experience and this is your first one
