If your grade one teacher sat you down, when you were mentally 6 yrs old, and explained the principles of algebra to you, told you the grammar rules of Spanish, or Latin or whatever language they made you take, and gave you the book of A Tale of Two Cities and told you to write a book report, why didn't you just understand all of it and enter 9th grade?
some people somewhere probably could, are you just a slacker? lol
Read my reply again. The two are contradictory. No matter how you get there or when.
