Digital notes are more efficient with respect to the time you need to make them when compared to written notes. Also, they are easily accessible, as you can organise them into files and folders according to their relevant subject and, more specifically, according to their relevant concept/module/topic. Additionally, the fact that you will need to go through your notes on multiple occasions (instead of only once) will result in you becoming more confident and comfortable with your understanding and ability to effectively manipulate content from your respective subjects, irrespective of the type of notes you end up making (i.e. enhancing your memory). I would perceive this from a time management perspective (time feasibility). For instance, if you choose to write your notes, will you be able to effectively do so in a timely manner?
From my experience in the HSC and at university, I personally found digital notes to be better overall, particularly in the long term (mainly because I needed to come back to and revise those notes at some point in time). However, this doesn't mean that I didn't utilise handwritten notes to supplement my learning, particularly during year 12. I used handwritten notes to a much lower extent at university than I did in year 12, mainly because there is a very wordy aspect to my degree. Of course, I believe that handwritten notes would be more beneficial when studying/revising/preparing for subjects such as maths and science, where you may be required to draw certain shapes/graphs/diagrams, meaning that it would be a good idea to make handwritten notes for those subjects as that would constitute a good attempt to master a particular concept/topic or improve where required. This would be applicable to both year 12 and studies beyond the HSC, such as university studies. For any other subjects that don't involve such elements, I believe that digital notes would be both more efficient and effective in terms of your studies.
I hope this helps!
