Can i ask for further clarification on an answer

Hi Al Gallucci!

The discussion area underneath videos and articles that are relevant to the test may be helpful to take a look at and ask general questions if you don't understand a topic. Instructions to find the discussion areas can be found here: https://support.khanacademy.org/hc/en-us/articles/4411209335181-How-can-I-access-discussions-under-articles-and-videos. As of right now, discussions can only be accessed from the Khan Academy site. 

Additionally, you may be able to get some help on a specific problem by posting in the Study Group forum. 

I hope this helps! Please let me know if you have any further questions.
