Stable income: Somewhat stable

IELTS coaching online can be a moderately stable source of income for those who offer it. Based on online research and industry trends, many coaches experience decent baseline earnings but may face some fluctuations in income. While some months could be more profitable than others, overall, there is a level of predictability. Setting up online IELTS coaching can be affordable, with costs ranging from $100 to $500. If your best friend quit their job to pursue this full-time, you might say it's a moderate risk but with potential for consistent income. I'd rate it a 3 out of 5 because while it offers decent stability, there could be fluctuations that impact monthly earnings.
