Beginner friendly: Moderate

I’d rate it a 3 because Testable Minds is a platform where individuals can participate in academic research studies for compensation. While it doesn't require special skills, it does require time and effort to find and complete studies. The availability of studies can be inconsistent, and the pay per study may not be substantial. However, with dedication and regular checking for new opportunities, a beginner can start earning some money. The process is straightforward, but the income potential is limited, making it moderately easy to start earning a profit.
