At Home Minimal equipment template week 6 - Am I doing something wrong?

I completed the circuit on week 6 in 4 minutes, however, I noticed there was a 10-minute cap. I used a 20kg dumbbell for the squats (taken just below parallel) and did strict, chin above bar overhand pullups. Am I meant to keep repeating this circuit until the 10 minutes are up, or is the circuit for this week just meant to be a less difficult one?

Many thanks for the constant support as you have kept me training through quarantine! Gyms still won’t be open for some time in England which sucks:(

Sounds like the squats were pretty easy for you and it would be nice if you could use more weight. That said, it’s meant to be done as fast as possible so you’re doing it right.
