Why do non STEM majors detest taking algebraic courses at the collegiate level?
yKpoI14uk [10]

Answer:

Because they find it hard to pass in the past.

Step-by-step explanation:

Non-STEM majors detest taking algebraic courses at the collegiate level because based on their past experiences in high school, whereby they probably do not excel in algebra, numbers, or mathematical subjects in general, the thought of going through advanced numbers and equations can be overwhelming.

Nobody wants to have or at least start college with poor grades. Hence, because non-STEM students find algebraic courses hard to pass in the past, they detest taking the course that has to do with it at the college level.
