Tell HN: Studied computer science but struggled with statistics, and algorithms

Hello guys, In college, I put my classes in 3 categories.

The Naturals:

Topics I could do in my sleep: GUI classes, Programming Classes.

The conceptuals:

Topics I understood the concept of:

Database, Physics, Computer Graphics, Biology.

The Aliens:

Topics I couldn't grasp no matter how hard I read the books.

: Statistics, Probability, Algorithms, Calculus 2.

These topics are what make me afraid to apply for a job. I can code, but I do poorly in interviews.

Thanks.
