I have finished a few economics courses in my university before and I highly doubt this is something you wouldn't be able to do yourself. Unless you literally spent the entire semester completely ignoring the course, you should not find the material to be hard. An introductory course to economics is something that even high schools offer as an early college elective nowadays.
Regardless, how long is the quiz and how much time do you expect it to take? I am not planning to do this for you myself, but this kind of information is expected if you want to strike a deal with someone.
Please, lay off that judgmental attitude. I've been working hard all semester. I haven't ignored the course.
If you already know the course, it shouldn't take that long.
The length of the quiz I can only reveal in PM as I do not want to be dismissed for academic dishonesty after having someone from the school see this post.
If this is what you fear, then you wouldn't go this route trying to pass because you don't know who will be contacting you. By just the little information about the test you have there, some people would have known already the nature and even the exam you talking about just looking for evidence to back it up then nail you. Not everybody on the internet or forum like this would want to encourage behavior like this especially if he/she labored to get his own score.
I am not judging you, but I am saying be careful who you want to give more information about the test and more of your details.
