Information regarding algorithm on actual test

Hello!
So, I know that the first quant and verbal section that we get on the actual test is on medium difficulty. So, I was wondering: How many questions should I correct on these questions (out of 20 verbal and quant) so that I get medium/hard next section?

@keenabdulbasit Did you get the answer?

there is a video by GREG on this topic on Youtube.

Is it the same video in which he explains that 3rd party material is pathetic?

no, it is different.
