You are likely to be required to write a quick essay in order for a college or university admission board to judge whether you have the writing ability to study in their institute. Now you can consider yourself fortunate if you have worked on your writing skills through out your education. In the case that you are not confident in your writing skills it is a good idea to work on them. Your school should have an academic writing department that can assist you in improving your writing skills. The academic writing department should be able to provide you with hand books, notes and outlines as well as sample essays. Use these to learn how to write.
