Stable income: Somewhat stable

An online tutoring and test prep coaching business can provide a moderately stable income source for most people who try it. Based on online research and observed trends, individuals can generally expect a decent baseline income with some variability month to month. While some months may be more profitable than others, there is a level of predictability in earnings. I'd rate it a 2 out of 3 because while it offers a reliable income stream for many, there can still be fluctuations that prevent it from being considered very stable.
