Once you have ensured that you have included all the components of the cover letter, and that it gives a clear picture of your accomplishments and what you have to contribute, do a final proofread for grammar, spelling, and correct format structure. For additional feedback, bring your completed cover letter into the Career Centre for a consultant to review.
TIP: ask at least two other people to look over your cover letter. A fresh pair of eyes will be able to point out mistakes that you, as the writer, can easily overlook.
