I have a common problem that whatever I study, I am not able to retain it later.
I understand the learning outcomes at the time of study (or I am under the illusion of this), but after some time (some hours/days/weeks), the learnings are completely siphoned offs.
I have tried to revise, recap and practice, but I see that these decrease the productivity (i learn a lot less in given time), and I am able to retain for some longer time (and not till eternity).
With the amount of Information I have to grasp, I forgot what i learned 2 days ago, and go back to the material again, when I need to actually use that learnings.
My question is how to increase retention power? and Does sites like lumosity(or any other alternatives) really helps
