To look up your grades and feedback for SCI 199 L0161 on the web, you need to formulate a "username" and "password" specially for this "netgrade" program of mine, as follows. Do not use your ROSI password (or any other password). You should not type your ROSI password into anything but ROSI.
Your "username" is the first five letters of your surname (or all of your surname, if it's less than five letters long), removing punctuation and spaces, all lower-case.
Your password is your nine-digit student number.
or there is an expanded version of this web page if you're having trouble or the above is unclear.
