<p>The way I see it, </p>
<p>what might hurt you, is the fact that you only took one AP class in Junior year and three AP in senior year. This course load will probably not earn you the designation, most difficult course load taken from your counselors. It also seems Northwestern will not get to scores on the three AP courses you are taking or how well you are doing in class in senior year. </p>
<p>On the other hand, I think your SAT scores are good & interest in mathematics is apparent. You also have the Hispanic hook which can help.</p>
<p>In conclusion, I would think you have a chance of being accepted, but not very high. However, even if you do not get in now, you could attend a community college, get straight As and apply as a transfer student. At that point your senior year AP classes would show up on your high school transcripts and they would back up what the community college transcript will suggest, that you are ready to tackle the most difficult course load in college.</p>
<p>By the way, my son is in a similar boat as you.</p>
