<p>Do I have to take all three in the same semester, or can I take chem 130 first semester and then take 125/126 second semester?</p>
<p>I believe it’s merely recommended that you take them cocurrently, not required. The same goes for most courses that have a separate lab class. For some classes, it’s easier than others because the lab material is less integrated with lecture material and the lab acts more standalone. I don’t know what the case is for chem 130/125/126.</p>
<p>D took it last semester. She said it would be recommended to take at same time, but you could take 130 the first semester and 125/126 the next.</p>
<p>How many units are you planning?</p>
