5. If Level = 1 (Do 6 7 8)

On line 5, the event do do line 7 doesn't do anything. Line 7 isn't a onVariableTrue / onVariableFalse event.
For the EXP checks, you check twice whenever a bot is killed. If the player has >= 150 exp, and if the player has >= 250 exp. If the player has anywhere from 150-249 exp, the player will level up once whenenever any exp is gained. If it's above 249, then the player will gain two levels for each increment of exp.
