Many candidates make mistakes when they write a statement of purpose. If you want to do everything right, obey the rules. Write interesting, find in yourself the qualities and skills that will set you apart from the crowd. You will not look unique unless you yourself write about it. Any project or work can become a huge advantage.
Also, never leave your work on the last day - you will need time to check and edit your paper. If you do not have enough time or skills to test your work, contact a specialist. You can order help in the sop proofreading service.
