BSC 310 Specific Question

<p>BSC 310 is listed on course look up as a 3 hr class.
BSC 312 is the Lab… Some sections listed as 0 hr… Others as 2 hr.
The catalog 2012-2012 has 310 listed as a 5 hr class.
Son needs 310…
My question is must a 312 Lab be taken with 310?</p>

<p>I would email the prof and ask. Does his major specify if he needs the lab? I wonder why some are listed as 0 hours and some as 2 hours. Are the labs the same length of time?</p>
