Yes, I know this has been asked before but I'm still confused. Every application form I fill in has the section - Why are you applying for this post? So obviously you fill this in selling yourself to the school. I take it you do not need a letter of application as this would contain the same information as in the "Why are you applying" section. However I also believe you would need a covering letter - what would this be? Just a letter explaining you are applying for the post or would it need more detail? And of course, I now know about the executive summary. Second - if a school mentions a letter of application, what do you do with the section "Why are you applying for this post?" - do you state please see letter of application? Surely you don't want to duplicate this section?
