Does Bio lab take up the whole 3 hours?

<p>I want to take a class that overlaps with my bio lab for the last 20 minutes. Will this be possible? Thanks for answering :D</p>

<p>Doubtful that the labs will take that long, however i have been stuck in my chem lab 1 time were i could of used an extra hour. I dont recommend it. also, the worst feeling in the world is finishing a long ass lab, only to have another class to go to afterwards. choose wisely</p>
