[Marvel/MCU] Is Captain America the smartest a human can possibly be?

I know the combination of the super soldier serum and vita-rays was designed to make everything about him the peak of possible human perfection, but does the same apply to his mind as well as his body?   
On that note, exactly how much did the process effect his personality and way of thinking? Is he still the same person as before or is he someone new?

It gave him a peak human mind as well as body, but it did not make him any smarter technically. It really just made him a genius, in the sense that he has the ability to learn faster than the average human. He has used this ability to be a great battle tactician and pretty much a leader among any ranks.

It has changed his thinking to that of a more easily taught person. He might in the past go into a battle situation with a plan, and I'd that fails he regroups and thinks of a new one. With the way he is now he would go in with a more developed plan, that develops even more so over the course of the battle, and if he inevitably did have to retreat, he'd be retreating with a plethora more infor action than he would have gotten previously.

He's a new person, a greater version of himself.
