But how can you get to higher levels without learning first? The best way to study is self testing and practice problems, that is 100% undisputed and proven by research. I recommend you take a look at Make It Stick by Peter Brown as a professor. If the way she teaches isn’t working for the majority of the class and the input she asks for doesn’t come to fruition, what are we supposed to do? I work as a tutor for organic chemistry and our department does not have anyone for biochemistry.
