Skill Level Up Cheat Code???

testingcheatsenabled true, maybe?

i dont use cheats, so wouldnt know.

No such cheat exists. To raise skills, I suggest using testingcheatsenabled true then shift-click click the mailbox and 'make needs static'. Let your Sim read a gardening book or three for a day or two with no potty breaks. That should put them at level 10 ;)

Here is another more convenient way to "cheat" to raise skill levels. It works VERY well!
#1 Set each Sim in a household to do something that will increase the skill you want them to gain(studying cooking, talking in a mirror for charisma, playing the guitar etc.)

#2 Save the game and go into edit town

#3 Switch household to another house.

#4 Play with that other house for a little while. Then leave them doing something to increase a skill that you want for them to gain as well.

#5 Save game again and go back to edit town

#6 Switch households back to your original house.

#7 Depending on how long you played the other household, your original Sims will suddenly have increased up to 9 points of the skill that you left them studying!

(#8) When you go back to the house you switched to they will also have a big increase in skill levels as well.)

This works well in cities where you are playing multiple households. Have fun!
:lol:

I use the NRAAs Master Controller Mod.

Click on Sim > NRAAs > Master Controller > Advanced > Skill Levels

Very easy to use and convenient for making custom made townies that actually have skills and whatnot.
