Study Points

Study points are a way to increase stats in each of the protagonist's skills in Yandere Simulator.

Gameplay[]

The player gets to distribute study points to five different subjects during class time, when the protagonist is sitting at her desk. The classes start at exactly 8:30 AM, however, she can sit down at her desk earlier, which will automatically take the player to the study points distribution screen.

When the protagonist goes to class, she will receive a number of study points that the player can use to spend in each school subject. The number of study points she receives depends on her punctuality. Normally, she receives five study points when going to class on time or ten study points if she wears the right type of panties. Additionally, the protagonist can also earn 1 study point by studying with the book in the Library and passing 30 minutes in-game time that is also doubled by the panties bonus. If the protagonist is in the Gaming Club, she can play an educational video game to temporarily raise one of her subject levels for a day. If the protagonist arrives late to class, she will be scolded by her teacher and will have fewer study points to spend, the amount depending on how late she is; arriving from 8:31-10:00 AM will give her only 4 points, and 1 point less by each hour afterwards.

To level up a skill, the player must allocate twenty study points in a skill category. Each skill, when leveled up, will open up more methods and buffs for the protagonist to eliminate students. The game is structured so that if she attends class every single day on time for ten weeks, then on the final day, she will have maxed out all her school subjects.^[1]
