Two Point Campus

While playing Blundergrad, you will eventually be notified that a Mole is on campus and offered a quick guide on them. Once you know there is one present look around the campus to find students that have swirling white symbols above their head. The Moles might not show like this straight away so just have a look around every minute or so after you're told one is present. Once you find the students with the symbols you need to figure out which of them is the Mole. You will usually find them in rooms so what i usually did to find out which one was the mole was to slow the game down to the slowest speed and watch as each person leaves the room. If they leave and the symbols don't transfer to other students and disappear shortly after, then they're safe forget about them, if they leave and students in the hallway suddenly get the symbols then they are the Mole and you have to expel them! This becomes complicated if other people leave the room at the same time as the Mole so try to keep an eye on all of them and notice when they go in different directions to identify which is the Mole. If you have two possible candidates walking together you can select one and select "Send to Private Tuition" to possibly send them walking in a different direction. Sometimes the symbols will just disappear completely. If this happens just start over and search in another minute or so. You will have to do this three times as part of the Blundergrad star requirements.
