Questions about ranking system


Hey guys. Im pretty new to faceit. I just got into it this month. I bought premium and noticed there were 2 different queues. One was 5v5 and the othee was 5v5 premium. What is the difference between these other than premium plays on anti cheat?

Im level 7 in rank silver and idk how to get out. Ive played about 50 games and have a 75% winrate with 1.7 kda. Its fun being able to dominate these bots but i wanna play against equal or better conpetition. How long does it take to get to master? Can you only rank up one rank each month or can you skip ranks?
