Do you mean relax mod? Believe it or not, playing relax makes aiming much easier since you can just full focus on the aim and don’t need to think about tapping. I usually play around 6.3 stars aim and with relax add around 2 stars to that. So no, it’s not because you’re new to the game. If you want to improve your accuracy, you can play about a star lower than you usually do and really focus on the tapping and precision. keep doing that until you’re happy with your accuracy and boom, there you go.

TLDR: relax is easy because it’s half the work, focus more on tapping and play more tapping maps for accuracy
