Hate this first year in my group

Just wanted to rant about this girl in my first year class

1) she is the only one that’s condescending towards everyone in the group
2) she looks down on every other first years and loves kissing second year and others ass, she openly kisses the seniors ass and acts like she knows so much about the group
3) she cries every other day and pretends she’s the smartest one in the group
4) she think she’s cool and acts like a boss
5) no first years like her
6) dirty too and sick every other day
7) overworks herself and than acts like she the shit because she works a lot

No first year likes her, how do I tell the seniors these toxic shit she’s doing

Can I punch her in the face?
