Will this ruin my chances?

<p>I am a sophmore in high school. I would like to go to either UCLA, UCSD or San Diego State.
I am having a delima. Here are my grades from freshmen year.</p>

<pre><code> First Semester Second Semester
</code></pre>

<p>Pre-Ap English: B A
Pre-AP Geometry: B B<br>
Pre-AP Physics: A A
Health: A
World Religions/ Geo: A
Dance: A A
Drama: A A</p>

<p>I have chosen classes for this year. I chose
Pre-AP English 3-4
Pre-AP Algebra II
Pre- AP Chemistry
AP Euro
Dance Production
Spanish 1.</p>

<p>I play volleyball. And if i take all those classes i will be overwhelmed. So if i changed AP Euro to CP World History will that affect my chances of getting in to any of the colleges i want to go to?</p>

<p>Playing sports and balancing school work is a very important part of high school. I’m a professional skier, and during the winter, I ski about 6 days a week on average. Managing work during those times is pretty challenging, but I still have a very rigorous schedule. Moreover, you should definitely take at least 1 AP class your sophomore year and if Euro is most readily available then you should definitely take it.</p>
