Should I retake the Physics Regents?

<p>I'm a senior this year and did poorly on the Physics Regents last year. All my other regents are mastery (85+). The only time I can retake the Physics Regents is in January (probably mid January) but is it still worth it? Because I know many college applications are already due in early January. Will retaking the Physics Regents even matter anymore? Can colleges still see the new grade? Also, how much will one bad regents grade affect my chances?</p>
