There is a total of 80 General fight trials to get this achievement, 10 in each category of 8.
To unlock this achievement you must get 60 LVLs complete.
NOTE: Not everyone will get the achievement at 60, this can be glitchy as I got my achievement at 61. If you do not unlock the achievement at 60, just keep getting more done and it should unlock.
Note 2: Since it changed to season 2 everyone with ANY general fight titles from SEASON 1 has reset, BUT you still have the same progress towards the achievement, just keep unlocking the new fight titles and you will obtain the achievement when you come to 60 with season 1 and 2 combined.
Note 3: For everyone starting or continuing Killer Instinct, when they were reset for Season 2, the fight titles were made easier, so using my guide below, do understand that the requirements are different, you can still follow my solution, it will just be easier then how I put it.
There are Fight titles for every character, and then there are general fight titles, to view all fight titles, go to
Fight Archive->Fight Titles->General
This achievement was no problem at all for me, so I will just give which ones I did to get to 60 and how I did them.TOTAL KP EARNED
TOTAL MATCHES PLAYED
CONCEPT ART COLLECTED
PRACTICE MODE MINUTES
SURVIVAL ENEMIES DEFEATED
If you don't want to get the achievement extremely fast and are willing to wait, you can just go for the other achievements and you will eventually hit LVL 10 total matches played (5000 matches).
Also in RANKED VICTORIES you can get 2 more towards the 60 if you wait until you have all 6 characters 20 wins which will be 120 victories (LVL 7)
