I am a chemistry student at university and have finally hit physics. I have been able to handle the calclulus, chemistry, biology and other courses; however with physics I have had to put much more effort and time in order to master and understand the concepts. Is this normal? I feel consistently inadequate, I have never had to study so hard for such rudimentary skills. It's not even the calculus based physics either, its a prereq for calc based physics. I guess my question how natural is physics to you? Of course this is a physics forum so its probably very biased but I would still like to know.
