many ths! questions about PHYSICS summer session course

<p>Hello, I am a EST sophomore and going to take the summer sessions at UCLA. I came across some questions about course choosing, and I really need your help. Thank you!</p>

<p>I major in ELECTRONICS and I decided to choose PHYSICS 1B OSCILTNS&WAVES&FLDS. There are two types, LEC and DIS. Both course discriptions says “Lecture/demonstration, four hours; discussion, one hour.”,while both courses are 1-hour course. And I find that some other LEC course discription says" 3 hours", no discussion. What does that mean? And does LEC involve little studet participation and communication to the teacher?</p>

<p>Also, I find the PHYSICS B DIS is of 0.0 unit… what does that mean?</p>

<p>Besides, I wonder wheather to choose PHYSICS 4BL LAB-ELCTRCTY&MGNTSM or not. I am EST student from Asia, I want this lab opportunity but i am afraid i can’t handle it. Please give me some advise. and tell me the exam pattern, paper? performence? writing test? practice test? and I don’t study electric, is that matter?</p>

<p>I choose a EST wringting course, and all the units add up to 11 units… is that too hard for EST student?</p>
