Solve this challenging aristocrat straight out of my cryptography class.

ANUYJKHNFL JLNBL, NBENJK YNK KHNKIONS: JNYNHYJ - SNJKONS, INHKONS, JNHDSNJ ONBRNJ!
the letter 'E' does not appear in the plaintext
the 3-letter word is 'BUT'

Dang, I couldn't solve it without the hints :(
dumbstruck skunk, unjust but truthful: suburbs - lustful, hurtful, surplus fungus
idk how would you approach solving this without the second hint?

Also y'all have a cryptology class :o

Solve this challenging aristocrat my partner gave me awhile back pertaining to a subject taught in school:
GRKV EUPVYI SRYF FWBEAVFQAERV PVRB, NEABZVRKH GRKV VFQAERBU PQAKH SRYF FRHFQW JQPDDPCQU HPI.
The ciphertext H corresponds to the plaintext G
South Woods MS, Syosset HS '21
BirdSO TD/ES
Past Events: Microbe, Invasive, Matsci, Fermi, Astro, Code, Fossils
1st place MIT Codebusters 2019-2020
1st place NYS Fermi Questions (2019), Astronomy and Codebusters (2021)

So I realized that this is probably too hard so here's a hint I gave out earlier:
The last word is gas
If that isn't enough:
 The ciphertext F corresponds to the plaintext H

thanks for the hint lol, sorry it took so long to respond

i very much wish i wasn't atm :( also, why is this ciphertext so long?!?!?! i solved it as an aristocrat ngl
A sysadmin once suggested to another sysadmin that they should add a doomsday countdown to a giant display used for monitoring school services. The older sysadmin misheard the first and thought he was asking for a tuesday countdown. Since then, the upper right corner of that display has had a tuesday countdown, and it's not going anywhere anytime soon.
decipher this vigenere with a 4-letter key word of something my physics teacher said about a senior tradition of not going to school. the sixth, seventh, and eighth letters are "RE G"

I'm guessing the key was SKIP... While solving I guessed on some words so they might be wrong but:
If you're going to take a skip day, don't call in sick. Just own the unexcused absence. My son once drove to Philly and got a cheesesteak on his skip day. Might be wrong but I tried
Also when I solved "idf'd i got aon'n" which didnt make sense in the sentence so I just changed it to what I thought fit the sentence

Since no one has gone in a while, here's a question:

Alexa misheard you reading a snippet of text off Scioly. Her transcription has been encrypted using monoalphabetic substitution. What did she think you said?
