Stable income: Somewhat stable

I’d rate it a 3 out of 5 because while there is a decent baseline of income from regular students and classes, it can be unreliable at times due to factors like student retention, seasonal fluctuations, and competition. It's not as unpredictable as a 2, where income would have wild swings, but it lacks the predictability of a 4, where most months would be similar and dependable.
