Learning is quite a reverent topic. I am an excellent student and it is important for me that I have enough time for each item to master it. But sometimes time is simply not enough ... Therefore, you have to write a daily routine in order to somehow plan your time. I even bought a special pocket notebook https://onplanners.com/planners/best-academic-planners-colle... for this. It is very convenient, you can record any information in it, it does not take up much space. So who has problems with the allocation of time, I advise you to write yourself daily routines)
