While you claim this is bad advice, there is a similar chat on this thread - starting on 54 (there’s a few below).
If you submit a 32 to a school that has a 33, you’re brining down the average - and no school wants their # to go down.
I don’t know the right answer…I’m not sure anyone does.
But to say it’s just bad advice runs counter to what many posters historically have said - and there’s discussion / debate about this exact scenario on this other thread related to similarly difficult to get into schools so OP might find it relevant.
