For my BS, I paid people $70-90 to write essays for GE classes..

Is this wrong of me? Should I have written that paper about earthquakes myself?

Meh

Only if earthquakes were a big part of your life since.

i'd kinda say yes, u should have.

1. it might have helped you better yourself at writing.
2. it would have saved u 70-90 FREAKING DOLLARS 😦😦

Yes. Who cares about the earthquakes. It's about learning how to write properly, and articulate your thoughts and ideas clearly and convincingly.
Definitely a missed opportunity, but you can always make up for it now. Just write them for yourself.

When you say, "my BS"...

Are you talking about a degree, or...?

Cheating is nothing to brag about. If the wrong person finds out, this can have bad consequences.
