Chuck here, from the Common App support team. I've noticed a few questions asked a couple times on this thread as well as submitted to our support desk, so I thought I would jump in and provide some clarification on those common topics.
Issue/Question: Unable to login or getting errors trying to login
Response: There are two things to note about this. First, accounts from last year will not work anymore; a new account must be created. Second, some of the pages from last year's Common App are still "cached" by Google or your own browser if you visited in June. If you go directly to
https://app.commonapp.org/ you should be ok.
Issue/Question: You participate in more than 7 activities or have more than 6 previous jobs. Where should you enter additional activities?
Response: There is an Additional Info area in the Writing Samples section of the Common App for this purpose (or to capture other information that would not fit in the main Common App fields). If you have just a small amount of additional information to provide, use the short answer text field. If you have a lot of additional content, use the Upload Document button to upload a file (e.g., a Word document, a PDF file, an RTF file).
Issue/Question: Can you submit a different personal essay to different schools?
Response: You cannot submit a different personal essay to different schools. The document you upload in response to the personal statement question will be the same for all submitted applications. Note: for those schools that have an online supplement and additional essay questions, you can, of course, provide school-specific responses to those topics.
Issue/Question: What to do if you indicate the use of a NACAC/College Board fee waiver incorrectly.
Response: If you indicate that you will be applying for a NACAC or College Board fee waiver for one of your applications by mistake, you will need to contact technical support by clicking on one of the 3 "Help" links located within the Common App Online. We can then remove this indication for you as that is not something you can accomplish through the website at this time.
Best of luck to everyone in the college application process! If we can be of help to you as you work through the Common App, please don't hesitate to contact us.
