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...

Stu it's not the same RPM shift at every speed.. look at any RPM vs Speed graph for all gears and you will see they are not parallel - here is an
example
