How many A.P.'s do I need

<p>My school offers a total of 25 A.P.'s, however by the time I graduate I plan to have only taken 13 will this be looked down upon?
I’m looking at top-tier schools like Harvard, Yale, U chicago, Cornell, ect…</p>

<p>Also does taking 8 Senior year help or does not make that much of a difference?</p>

<p>Taking 13 is PLENTY. You don’t need to be narotic and take all 25. My school offers 17 but I will have only taken 8 when I graduate. Use that extra time to do some good ECs and do well in all your classes.</p>
