<p>Hi, is LS 23L a corequisite to LS3 or LS4? </p>
<p>I am planning to take Psych 100B and Physics 6A together next Fall, both of these have labs, what do you guys think? Do-able?</p>
<p>And, also, when can we actually start taking the electives? Can we get credit for them even if we haven't been officially admitted to the major or if we haven't finished all the pre-req.?</p>
<p>Thanks:)</p>
