I am applying to a Master's program using an online application where I must report my prior university education. The field to report my undergraduate GPA is not required and would anyways be verified by using my transcripts before admission. It would, however, be more convenient for the application committee to get a feel for my undergraduate record if I were to report it voluntarily since they would not have to immediately match my application with my transcript. It should be noted that other materials (like a statement of purpose) are separate documents.
How will reporting or not reporting affect my chances of admission? Are they more likely to reject an application where they can immediately see a lower GPA, or one where they are unsure of what it is at first? I feel that my GPA may be a potential weakness in my application and would prefer not to have it advertised.
