Undergraduate advice

[Unknownmember]

Hi, I’m currently an undergrad in first year studying applied math. Due to circumstances out of my control it’s likely I’ll finish this year averaging about 55% as my studies were affected, I have the option to switch to a double major in pure math and econ and start fresh. My question is should I do this as I’m worried employers might look at my first year grade and turn me down.
Thank you
