The bankai mugger: Cannot stop mugging, and cannot take any breaks! Only 100 more days to A-levels rawr!
The closet mugger: These people hide at home to mug, so that no one sees them mugging. They would then tell all their friends that they are going to fail the exam before walking into the hall, only to slap them in the face a few weeks later with a "Wow, I got deans listed without studying!" Rarely contributes in class either, in order to cover their mugging tracks.
The construction helmet mugger: No one really knows what the helmet is for, but some say that the helmet is there to prevent any brain from exploding. Others hypothesize that maybe the helmet keeps them from falling asleep. Seriously, try sleeping with a helmet.
The group mugger: Some people just cannot study alone for some reason. They have to be sitting in a group before any work can be done. Admittedly, a big advantage to this arrangement is that you can ask people questions. However, people might ask you questions and distract you too. Pick your members carefully!
The legendary mugger: Legend has it that there was once a guy who got UUUUU for the last exam and suddenly goes into a mugging frenzy. The result? Straight As. All muggers hail this mugger, for he have done the ultimate 25 grade jump. His name is carved on the library wall, so all knows about the new legend.
The midnight mugger: Sleeps during class, but still scores very well. What is their secret? They do not sleep at home! Instead, they spend their nights burning the midnight oil. Three cheers for caffeine.
The mugger mugger: These sneaky bastards camp outside the library at night with a baseball bat, ready to knock out the next guy who comes around the corner. This explains the construction helmet mugger!
The mugger mugger: Huh? Did legendary speller Huang just make a mistake? Did he not just educate us about the mugger mugger? No! This mugger mugger is different. They also stand outside the library at night, but they are actually there to take notes about sneaky bastards who camp outside the library at night holding base ball bats.
The musical mugger: Why is that dude wearing headphones while mugging? His head is bobbing up and down to the beat, I guess some people just work better with music. Not to be confused with a silence mugger.
The poor planning mugger: Unfortunately, some of the muggers are just not that good an arranging a mugging schedule. This ends up in them pacing themselves so badly that they spend too much time on one subject and have no time to do anything else. A typical report card of a poor planning mugger would be: A (Mugged for this yo!) C (Can't possibly suck at everything) UUU (But sure can suck for 3 things). Ouch.
The proud mugger: Spams you with tonnes of knowledge that they have committed to memory. When they start mugging for general paper, be sure to hang around them as the spew bits of information that might come in handy. Remember to stroke their egos by telling them how smart they are once in awhile if you want to keep them going. To stop them from annoying you, talk about a subject you know they have not touched.
The silence mugger: Why is that dude wearing headphones while mugging? Cannot possibly be to listening to music right, what sort of weirdo can study with music blasting in their ears. I guess he just does not want anyone talking to him.
The sleepy mugger: Can be found sleeping on their notes in the library. Looks like he is going to be up all night. Feel free to grab any fancy mind-maps you see on the table, just be sure not to wake him up.
