So I've been accepted to the college I wanted to enter, but heres my problem I dont know what major I want to pick so I choosed undecided but I want to know if undecided major would cost me more, and how does an undecided major work because dont you need major's credit each semester? should I just select my major(computer sci, engineer) to try it and see how I like it, or am I better off starting with undecided major? I want the best results for time/money.
