This is a fun and a challenging was to get some points. All you have to do is duel another member from the academy and win. Once you have done this then, you will have to get some proof about it. For the proof, you can just ask the person you dueled to confirm it or get and imagur pic.
There are 2 types of duels you can do. First one is a arena duel. In this duel, the person who wins gets 20 points and the person who lost loses 10. However, in this duel you can duel in single or match. Futhermore, once you have dueled, you cannot duel the same person again untill 24 hours have passed.
The second type of duel is a betting duel. In this type of duel, you can duel as many times as you wish but you have to bet. So whoever wins, that person gets all the points. And whoever loses the duel, that person has lost those points. These types of duels have to be in match format.
If a player quits, then it is declared as his/her loss. However, if a player quits on betting duels then, its considered as if he has lost just that one duel out of the three.
There will be times when players will lose but don't let that discorouge you, remember, this is supposed to be for fun, its not a must.
For everything, you need proof so please don't forget that or all your efforts would have been for nothing. The last thing I want to say is nobody can force anybody to duel with him/her. If the staff finds out about this then you're gonna be temporarly banned from this site.
There are certain deck that you can't use. exodia, burn, stall, mill (excluding lightsworns). And also, you can't change the rules.
