which is code somone made it from our universty we add it to chrome from consule and it show us the grades of the exam even before the grades is open in the site

but i want to understand what it is and how to read it anyone can help ?

its obfuscated so the code is scrambled to make it hard to read.
i quickly deobfuscated it, so the real code is something like this:

oh that was so easy for you thank so much can you tell me how you did deobfuscated it

you need to decode the hex into readable strings and then piece it together.
on linux you can simply use "printf" to convert the HEX code to ASCII, for example: printf "\x70\x6F\x77\x65\x72\x65\x64\x20\x62\x79\x20\x53\xDC\x20\x3A\x29"
