Is it too late?

<p>Hi</p>

<p>I am applying for business management to:
-Univ of Illinois Urbana Urbana Champaign
-Indiana Bloomington
-Univ Wisc Madison
-Penn State
-USC
-Univ Mass Amherst</p>

<p>I am a senior and I have 85 gpa, 670 math 740 writing 630 critical reading. I participate in many clubs, but my main focus is on robotics, as I hold an executive role there. I want to know if it is too late to take the SAT again in December. I wasted my time and did not study for the SAT before, so I am hoping that I can pull off 800 writing and at least 750+ math and critical reading. Is this feasible? In addition, I want to take SAT subject test in January. Is this a good idea?</p>

<p>Thanks</p>
