<p>What's the difference?</p>
<p>Astro 10 is similar to Astro C10 in terms of content, but I don’t remember exactly (in terms of content) what makes them difference. However, Astro 10 is offered both semesters and Astro C10 is only taught in the Fall because Filippenko teaches it. Astro C10 is probably the one you want to take when people say that “you should take Astro”. Filippenko is highly regarded as one of the best teachers on campus to take, regardless of major.</p>
