Chemistry and Biology during Spring?

<p>Hello everyone,</p>

<p>I just started college and I signed up late for Biology I and Chemistry I for the fall semester.
I decided to sign up for those classes during the Spring semester, however is this a wise decision? I will not be taking any science classes during the summer, so if I do take Chemistry I and Biology I during the Spring sememster '13, I will be taking Biology II and Chemistry II during Fall semester '13. Should I do this or should I wait until Fall '13 to take those science classes so I can stay in fall - spring sequence?</p>
