<p>Hey abs</p>
<p>Most colleges offer 18-21 credits per semester. For understanding purposes, each class=4credits. That means most freshman will end up taking 4 classes in the first semester.</p>
<p>Let me try to expand on that. Each credit= 1hour of class approximately.</p>
<p>So a 4 credit class will have, roughly, 2 lectures + 1 lab/Recitaion= 3 sessions per week.</p>
<p>Which means four 4 credit classes = 12 sessions per week. </p>
<p>The duration of session varies from college to college. For eg. Since my D goes to NYU, I can tell you specifically about that, each classroom session is for 1 hour 15 minutes.</p>
<p>Hope that helps.</p>
