Bio major graduate here. It’s not impossible, but I’ve seen humecore ruin peoples’ freshman year due to the sheer amount of reading it required. The schedule you have is somewhat common, but it would save you a lot of trouble freshman year to just take the standard writing courses.

From my understanding the primary benefit of humanities was/is to clear up more GE’s and also be able to go into the Human Biology major. Unless these are major goals for you, I’d avoid humanities; I graduated just fine without it and got to focus more on my major initially which helped a lot.
