Learning routines are a good thing, but in some cases it can be useful to change the learning routine once in a while. Breaking the monotony and breaking out of the learning routine can increase the efficiency of your memory and help you output long-term information faster.
You can try to change the place where you study or change your repetition times. It’s not necessary to make a radical change in your learning habits, it’s enough to try something new every now and then to relax your mind and increase your desire to work.
