Question about shazam

In his powered form he gains the wisdom of Solomon which gives him incredible intelligence and memorization abilities as well as a unique insight to problems and battles which is why batman allows him to look after the team and why the other league members let him stay despite his age.

I'm also guessing if he bothered to do so he could become a master in various studies from technology to biology to physics and such, my question is if he learns and memorized various studies would his base form still be able understand and remember what he learnt? So if he learned and experimented with alien tech or about genetics like the meta-gene would he still understand and remember it in his mortal form? Or would he understand and remember only portions as his own IQ is lower so it becomes dulled or even out right no longer understands it?

P.s I pressed the wrong tag my bad!
