It it normal to like physics research better than solving problems for coursework? Is physics coursework in the U.S. is too problem-solving oriented? Thanks

Homework Statement sorry but I'm confused is it okay if i say 2 \leq 2 or 1 \leq 2 and this example i know this is true "if p is prime then p>1" but is this true? "if p is prime then p>-20" its true right? because the generality doesn't change

Say I enter PHD w/ an outside MS. What percentage of coursework can I usually transfer? How many semesters classes need I retake? I'm thinking of an MS in signal processing in EE, if that makes any difference. thanks.
