Hello Physics Forums! I am new to the forums, but have been reading on here for a few months now. I have a couple questions I was hoping to ask you folks: I am beginning my undergrad work in engineering at the young age of 28. My first question deals with just that: will it be frowned upon when I am applying to jobs in 4-5 years that I am in my early 30s? Anybody have experience with this situation, either self or known someone? I took Calc AP in high school 12 years ago and excelled. My advisor at the community college I am starting at recommends I jump right into Calc I, but I was considering doing the 2-semester PreCalc sequence first to re-familiarize myself with math. He thinks it wouldn't be necessary; that I could brush up on PreCalc concepts over this summer and be ready in the fall....any thoughts yay or nay? My third question is on working while studying. Since most of my education will be paid for by myself, is it possible to work during the 3rd and 4th years at university? I consider the design projects and advanced labs that will be part of the end of my studies and wonder if I will be able to maintain a work schedule as well. Comments? I welcome all questions, comments, greetings! :) Thank you all in advance!
