Do schools know how many others I've applied to?

When I fill out the Common Ap, can schools see how many other colleges I have applied to (and which ones). Also, are they able to access the # of times I’ve taken the SAT or ACT? Or, is this private??? Tx to all who answer.

Colleges don’t know what other colleges you’ve applied to unless they ask on their supplemental questions or in the interview. For the most part, they don’t care. Nor can they see how many times you’ve taken the SAT/ACT unless they require all scores, or unless your HS lists it on the transcript.
