On my Common App Application, for the section where it asks what academic programs interest you, vocational plans, and extracurricular interests, and it asks for you to rank how likely you these plans are to change, where 1 is not changing at all and 5 is very likely to change, I messed up. I misread the scale, and thought 5 was not changing at all and 1 was very likely to change. So I submitted a 5, 4, and 5 instead of 1, 2, and 1. Is there any way to fix this? I’ve already submitted my application. I was thinking about uploading a supplementary material with a document signifying my corrections, but I just don’t know. Help!!
I wouldn’t worry about it - a majority of students change concentrations and interests at least once at some point during college. I submitted a smattering of 1s and 2s as well as 4s and 5s IIRC (maybe a 4,1,2? Something like that) because I was very uncertain about some things when I was applying - it didn’t affect me. If it really bothers you, you could upload a short one pager saying you misread it and what your preferences actually are, but I doubt it will make any difference to them.
They mainly use your preferences to analyse what kinds of fields the incoming class as a whole is interested in (the Crimson posts an article every year about how many people are interested in SEAS vs humanities vs social sciences and so on in the incoming class’ makeup, and Dean Fitzsimmons often comments on how interest in X field/concentration saw an increase in interest due to Y program, and such). This also helps the university as a whole identify long-term trends in what their accepted students are interested in, to factor into policy decisions and future investment (such as the massive increase in interest in SEAS over the past 5-10 years) as well as identify if, for example, they’re struggling to attract students interested in certain fields compared to others, and so on.
@Telluric thank you so much! This made me feel much better.
If anything, I think you get “likeable” brownie points for realizing that things change and you likely will not end up where you started. I agree this is not going to make or break your admission chances.
The poster did not “realize that things change.” 
The poster tried to signify that things would most likely not change.
I think this is insignificant but you will feel better if you just call admissions and ask about changing it. If Admissions tells you not to worry about it, you won’t.
