I can’t find any information about different versions on common application. is it supported this year?
If you mean different versions of the essay or other parts of the CA, the answer is yes. You can make as many changes as you want in between submissions to different colleges. You can send a different essay to every school if you want (although I do not recommend this).
Changes will only apply to schools you have not yet submitted to. Important to stay very organized if you are going to make changes. It might be helpful for example if you would like to self-report SAT Subject tests to some schools, but not to others. Or if you want to re-order your activities for one application. Etc.
Thanks! but the URL doesn’t work, https://www.commonapp.org/CommonApp/Default.aspx?allowcopy=true
