Scholarship Loss?

<p>I am a senior from a high school in Eugene, Oregon. I have maintained around a 3.8 GPA throughout my first 3 years and first semester of my senior year. However, in this last semester I will probably end up with half B's and half C's on my transcript. I have almost 18,000 in grants to go to Santa Clara. Is it possible to lose this grant? If so, what are the chances? This is worrying me so thank you for the help.</p>
