If I am applying to a more selective college, will they at all consider things such as my literary publications and a blog I run which is about advocating literature? By the way, I wish to represent myself as someone excelling in physics and literature.
Blogging is very common and not a tip. There is no way to assess quality or significance (and that’s not number of followers.) What sorts of literary publications, where published, and what broad feedback from professionals? (Not contests but adult reviews.) Both aremost often also solo, not a true engagement of the sort top colleges want.
You offer no other background, so we no idea if this is a legit question. It takes more than some glitter to get into “a more selective college.”
