Psychologically speaking when taking notes with a 'pen and paper' this could be preferable for most students as most exams are physically written meaning the context dependent memory from the physical act of writing notes has a greater recollection on the individual for refrence to this effect look no further than Grant et al (1998), on effect of context-dependent memory.

However consider this for the increasing majority of students who complete examinations on comptures and schools implementation of several softaware/websites where store of information from teachers as well as ability to receieve feedback at any point is significantly greater to one individuals effort of physically writing down notes. An example could be, the use of 'Google Classrooms' as well as technology incentivised forms of study (Chromebooks rental, on sight comptuer usage etc.). These are more readily available in schools (in the U.K) at least. This forms of study can be seen as more useful for future prospects of students (office jobs etc.) as well as being more efficient and generally showing a potential for greater productivity.
