Former F2 frontrunner Sargeant was drafted in this year to slot in alongside Alex Albon and found it hard to match his more experienced team-mate while making his fair share of rookie errors.
But in recent races the American has made progress, most notably with finishing 13th at the Red Bull Ring and just outside the points in 11th at Silverstone, his best result so far. But the net result is that he's currently still the only full-time driver not to have scored a point yet.
When asked to sum up his season in Belgium, Sargeant replied: "Ups and downs, [I'm] not where I want to be.
"Over the last few rounds, I feel like I'm much closer. I feel like I've seen really good progression as of late and that's the most important thing.
"I think I need to clean some things up. I think, as a team collectively, we can clean some things up and that's what we need to focus on going into the second part of the season."
Sargeant has had to take his time adapting to the Williams FW43, which hasn't been the easiest car to drive and has lacked downforce compared to the competition.
"It's actually very, very small things but small things that make a big difference," the Florida native said when asked to expand on his driving style tweaks.
"There were points in the year where I was simply holding the brake too late into the corners and slowing the minimum speed down too much. I've gotten on top of that.
