I'm planning to learn two different things for this month. Due to time constraints and other factors, however, I am only able to read on one of them each day. My question then is that would it be better if I learned the 1st material first for half the month, and then go on to the other one? Or would it be better if I alternated between the two every day? Both would give roughly the same amount of time to learn each one (about 15 days or so), and I figured that that is enough time to learn the material. I am just not sure whether I should read and learn each material straight for 15 days or if I should alternate between the two.
