I must shоw my detаiled wоrk оn eаch question, аnd my writing must be legible. I may “borrow” results from approved sources, e.g., the textbook or notes, if I explain where I got them, why they apply, etc. It might be possible for me to skip a calculation and write down an answer if I explain with physical and/or mathematical reasoning how I know what the answer must be.
