fant94: I want to buy better drive
Before that, you might consider a short wedge - 1000% better than the Starter wedges.
"Pro tier driver"
Actually, the second driver in the Pro Shop requires Pro tier. Yes, Pro tier.
At 250 cr, it's very cheap but I'd consider it not worth the effort.
At Level 23, there are much better drivers available, and if you are on a tight budget, consider a 3WD as a surrogate with extra bonus on the FW.
"Tier promotion"
For Pro tier, you need six more ranked strokeplay rounds. With scores below 40, you will easily break the threshold in average.
From your score history, it looks like you play on a mobile app. That means that you may be promoted by XPs and level.
Have fun and stay safe!
