I'm an applied math and stats major. I had subpar performance freshman year and junior year, but made it up during my sophomore and senior years (graduated already and am currently working as a data analyst). My lower grades junior year were due to a string of personal problems with family and relationships, and I worked my ass off senior year (took more advanced math, and even the graduate analysis sequence at my school) to make up for it. That being said all of my grades are either As or B's. I received a c+ in linear algebra my first year, but I retook the class at another University (my school doesn't allow repeats for those who passed), and aced it. My in major GPA is around 3.5 as well. My undergrad istitution is well known, and also has a top 50 biostatistics program, but I'm looking at general stats, and undergraduate students don't really interact with the biostatistics Dept.
