The concept of “study level” is very subjective
does MSFS2020 provide a decent amount of material to use to practice things such as landings, takeoffs and basic vfr work, perhaps
does MSFS202 provide enough realism to practice a clean break stall (either power on or off) without spinning, no (ref Broken stall dynamics) or steep turns without crazy altitude changes, no
If you’re using it to supplement existing skill sets (ie practice vfr landings) it could work (though be very objective)
