Based on the context and the answer, generate a question. 

Context: A lot of my med school and md / phd classmates from both NYU and other schools across the country have really enjoyed teaching and interacting with the bright premeds in our classes . You also get the opportunity to help guide and mentor these students . Remember , you were in those shoes not that long ago so imagine how nice it is to have someone help calm you down when you are in the process of prepping for the MCAT . To make it even better , you can get paid quite a lot , with most first time instructors making around $ 33 to $ 37 an hour and you only have to work a minimum of 4 hours a week ( all on one night from 6 to 10 pm ) .

Answer:

They got to mentor other students .
