"Defiencies in courses"

Hi all,

I plan on applying to Arizona State soon.

On their admissions page, the school of engineering states:

Must meet one of the following three requirements:
Minimum 1140 SAT combined math and verbal or minimum 24 ACT combined score, or
3.00 minimum ABOR GPA, or
Class ranking in top 25 percent of high school class or
GED score of 500 or higher

In addition, freshman applicants must have no high school math or science competency deficiencies.
Please note: The B.S. in Informatics will allow one deficiency in either math or laboratory science, but not both.

It states that deficiencies in both aren’t allowed. What is a defiency? Is it a certain grade?

Thanks to all responses.

A deficiency would be either a D or F (non-passing grade) or not taking the minimum required science and math courses.

Wow, I am not sure how I completely missed that. Thank you Gumbymom!
