adsorb

You consistently use this where you probably want 'absorb'; they are not the same. Admittedly the usage is metaphorical, but learning something is closer to "take in or soak up by chemical or physical action, typically gradually" than it is to "adhesion of atoms, ions, or molecules from a gas, liquid, or dissolved solid to a surface". Presumably you don't want the information to just form a thin film on top of the learner.
