Trial experience?

Hi everyone.

My sim is a lawyer and is very wealthy, and I’ve found another job that will make her even wealthier, but she needs I think 90% trial experience. She only has about 50% and I have no idea how to raise her skill in it any more. Any ideas? :\ Thanks in advance!

Some other jobs in the law field add to the trial experience. I think so at least, because my character has it filled up to 100% and I didn’t extra study it.
