Material Science Research

hey scientists! Just wondering- when you were in grad school how many hours did you put into the lab per week? what about when you were taking classes alongside researching? I’m a first year PhD in a materials lab and a lot of my friends are doing biology centered research clocking some insane hours, but for me my research is very cut and dry when it comes to experimental work. Also, how much progress are people expecting me to make in my first year of grad school? Just a little nervous about falling behind
