Am I the only one here admitting that I don't always transfer pattern markings?
For darts I normally pin these straight away - two pins to mark the ends of the dart, one at the point and pin and sew straight away (always do my darts before anything else).
Notches - I only ever mark the armhole notches (if it's a sleeved garment) with a snip. Generally I don't ever mark any other notches, except maybe those on princess seams.
Other markings like circles, squares etc, if I do mark them, I normally use tailors tacks or carbon paper and tracing wheel. It depends a lot on the garment I'm making. Expensive or slippery fabric or a difficult pattern or something I can't afford to make a mistake - I spend more time on the markings. A simple pattern or "easy" fabric... minimals markings.
