Physics 253 (Modern Physics) Question

<p>Physics 253 is in the ECE flowchart for 3 credit hours. Also available is a PH 255, which appears to be a lab that accompanies 253 but does not seem to be required. Trying to verify that the lab is not required. Anyone know?</p>

<p>DS is a double major ECE/physics. The lab is not required for ECE but it is a requirement for physics majors. However DS advisor has advised DS not to take the lab and the class at the same time. Apparently it is best to take the class first and the lab the following semester. Can anyone that has taken the class comment on taking the class and lab at the same time or consecutively?</p>
