This can be quickly boosted in friendly matches with a friend by using forfeit.
Set up the friendly match in 9 Ball (other modes will work), set the number of frames to 25, then create a lobby. Once in the lobby, set your Aiming Level to "Off". You should gain 52xp each game. Have your friend forfeit the game as soon as it starts, then both players select "rematch". Rinse and repeat until the achievement unlocks. From level 1 this should take about a hour for both players.
Important: if you are pre-loading this achievement, note that it is bugged and will unlock a level before it should, e.g. it will pop at level 99, not level 100. The same goes for the level 36 and 66 achievements, and maybe the level 3 achievement (I didn't notice).
You will get these achievements along the way:
