Does taking two off-blocks senior year look bad for top colleges (i.e. HYPSM+)

That’s al little odd to take those subjects in the summer, admissions will typically look for those to be during the year, you may have to explain that, unless it’s covid related or something along those lines. Anyway having the off-blocks shouldn’t be an issue, in local schools here as an example, if you take a sport, which many do, you can’t a full course load anyway. You’re taking MVC as well.
