But “rwayt” could be “great” if shift r→g? No.

But given “pdf” at end, and you say “create paper” — maybe the cipher is just (or +19) to decode.

It looks like you’ve written a phrase in a simple letter-substitution cipher (likely shifting each letter backward or forward in the alphabet).

Hmm. Could it be (or shift -7)? Let’s guess the intended plaintext: likely “Please write a paper on…”, but not matching.
