What's the difference between seeming smart, actually being smart, and getting really good grades?

I think the difference between seeming smart and actually being smart is the person who seems smart isn't actually smart...but is there anything else? Can a person who is smart get bad grades in school? Someone once told me before that grades don't determine how smart someone is...|||This is a much more complicated question than it seems at first - it is really asking about what we mean by intelligence and there is a big debate about that. A person who is intelligent can have poor grades for a number of reasons. What about the following?



Beethoven carried on writing sublime music even when he became deaf. I guess he would have had difficulty picking up high grades in an exam which required listening skills. Was he intelligent? Well he certainly was exceptionally gifted musically.



We have all heard of the individuals who, after one quick glance, can draw complex scenes with amazing accuracy but they have immature written language skills. Should we call this artistic intelligence? They clearly have an exceptional gift of some kind but even a written art exam grade would probably be poor.



So, it is very difficult to differentiate between "seeming smart, actually being smart, and getting really good grades".|||a person who seems smart APPEARS to know everything about everything. but when one ACTUALLY IS smart,they don't have to prove it to anybody because they can prove to themselves that they're smart. and getting really good grades is a matter of studying hard and applying oneself to such study; besides, by studying and applying yourself to what you read, you get good grades, AND you get smarter!
