Unless you have a CVT of course.
OP (I will get flamed for this) try downshifting from 3rd to 2nd without the clutch.
Get rolling at ~35 MPH in 3rd.
Blip the throttle and slide it out of gear (the blip will relieve pressure on the gear stack)
increase revs by ~1000 RPM and ease it into 2nd (no clutch).
You will likely grind a couple of times trying this but unless you are using a gorilla grip you wont hurt it.
My bet is that you will get it before the 4th try.
Now that you understand that, experiment in different gears.
I have a video of me shifting from 1st all the way to 6th and back to 2nd without ever touching the clutch and ZERO grinding.
This is not a skill you would ever use in performacne driving, but it DOES help you to understand rev matching.
I drove my Karmann Ghia for months with NO clutch using that method.
To start at red lights, I had to turn the engine off, put it in first and start the car...

I feel like if the RPM gap was always the same, shifting from third to second at 10 MPH would take you from ~800 RPM to around 2700 RPM, since doing it at 60 MPH will increase RPM by about 2000.
