AP scores--are my chances demolished?

<p>A friend of mine(the only one from our school who was even waitlisted to Harvard this year) took 7. He said that was his only strength and recommends that everyone does the same. I’ll try calling the colleges I’m applying to and see what they say.</p>

<p>Would you suggest retaking my 2 subject tests to score 800’s? I KNOW I can do better on the math II test…but I don’t want to look like I’m obsessed with scores(my problem, actually, is that I don’t put enough effort into studying for these) What do you think?</p>
