<p>I have no specific information with regard to internationals, but I’m almost certain that Harvard wouldn’t rescind the offer if you dropped just one of your seven A-levels. TBH, they probably won’t even notice. In the US, revoking an admission probably wouldn’t happen for anything less than, in the most extreme example, a C or something.</p>
