As @BB stated, levels are a big grind in this high region, and it only becomes longer, see the table. Also, their only purpose it to release equipment, and you have plenty options now.
As for the tiers, the grind hasn't started yet. Min 40 rounds to TM, min 50 to Legend is "peanuts" against 500 to 1000 to advance further. But that is future talk.
Alas, I see a different problem:
All your scores are well above 70 (double the 9-hole-rounds) which is nowhere near the required 63. I'd say you need to improve on your game play. Equipment-wise there's urgency only with the §&$(! Starter SW (a L39 Taylormade 60° is a budget replacement), and you might want to change to custom balls for better performance and a slower swing speed - the cheapest are an improvement, but they cost continuously (wear and loss).
You may also look at your game management, improve strategy and shot selection - it's up to you. Select questions are,
- do your shots end up where you want?
- how many end up out of bounds / in water / in bunkers?
- is the risk / reward ratio good enough?
- is you putting rate less than two per hole?
There's plenty advice around here, and you may always post questions.
