Last week at the United States GP in Austin, the 22-year-old Tsunoda managed a ninth-place finish to get some points after starting the race from 19th position.
"Even if it does not help for the championship's fight with Haas, it was a nice surprise to get the extra point for ninth place in Austin, especially after starting down in 19th place on the grid because of the grid penalty, Tsunoda said.
"It was quite a tough race physically, but also good fun in the car, with a few nice overtakes as well.
"Overall, last weekend we looked quite competitive in the midfield, even if Qualifying was the weak point over the three days."
When asked about his thoughts on heading to Mexico for the weekend's racing, Tsunoda said: "The Mexican track I would say is quite unusual to drive, partly because of the high altitude of Mexico City.
"You run maximum downforce because of the thin air, but even so, it feels like you are driving with little downforce.
"I found that a little bit strange last year when I raced there for the first time, but at the same time I was able to adapt quite quickly and I remember I was happy about my performance, especially over one flying lap.
"I enjoyed Mexico, I liked the track especially the slow and tricky Sector 2 and I had fun with the car sliding around, which reminded me of karting!
"Getting it just right in the braking zones is very important. I'll miss out on FP1, as Liam is jumping into my car for that session, so the second practice session will be super important to allow me to work on building up my confidence in terms of braking.
"Last year I qualified in the top ten, but had to start at the back because of an engine change and then my race ended with a collision on the first lap, which was a shame. We need to have a good clean weekend, as we have to aim to score more points in the last three races of the year," Tsunoda added.
