<p>I hate to give you this vague an answer, but it really depends on the major you will apply to. I think that even if you dont end up using the credits, it may be useful for your app if you have a few 5’s, but if your’re asking this late, it means you’ve already turned in your apps and are waiting for decisions (unless you’re a junior). In general, most math science related majors want (or in some cases force) you to take their specific undergrad courses again. E.g. a math major would have to take the 1a-1b math series again, a bio/pre med the 1a-1b bio series etc.</p>
