For first point: can let the readers choose the main character’s name.
For the second point, can let the readers choose the main character’s major.
And for the last point, it does not matter which one is used, both are awesome educational institutions^^
College or University well depends.
If you choose University it’s cool because you can to the initiation haha.
And you can let the readers choose for the rest or go on the internet to search for ideas !
Male : Noah - Jacob - Austin - Asher - Blake - James - Charlie - Lucas - Jessie - Nathan - Oliver - Eric - Edward - Jake - Dylan… but these are some I like, you can search like list of boys name on the internet
Female : Lory - Stephanie - Dylan - Mindy - Mary… I’m lacking of ideas sorry . In this case, internet might be your best friend
