@BrownParent You stated “Schools are admitting you based on the proposed schedule, and some schools will hold you to it or rescind.” Not sure what you thought was redic to assume from that. I thought your statement was clear. I was trying to address OPs fear of messing up. OP didn’t necessarily mess up unless he/she will now be short of science requirements. OP changed his/her schedule, which is not uncommon. If anything material changes in app, one simply needs to update app file. Agree with @intparent’s statement. OP you have plenty of time to update app with that information PLUS any new positive updates such as a new honor, award, position, etc.
