Shifts in Person

I have a few questions about shifts in person.

Here’s the problems:

1)If one write’s logically, he will prove his point.

2)College students should act as adults and as such except our responsibilities.

Are these sentences correct, or not correct? If they are not correct, could someone please explain to me why.

Good morning.

  1. Appears to be OK to me.

  2. College students should act as adults, and as such, accept responsibilities.

Kitos.

Thanks man.
