Here are some common problems you might experience, and their solutions:
Problem: You have an agreed extension from your tutor but have previously submitted a draft version to Turnitin. When you try to submit a version after the due date, you cannot.
Solution: Contact your tutor. They need to delete your draft submission as only one more submission is permitted after the due date. LearnTech Support cannot do this for you without the written permission of your tutor, so please contact them first.
Problem: You have several documents to submit through Turnitin, but only one is accepted.
Solution : You need to combine your files as a single PDF. See : Submitting Portfolios
