Turin,
I mean, look at the questions. You would have to be a pretty spectacular 13 year old to write that sort of stuff in your own language never mind a non-native one.
You need to go back to school and have a look see. Today, pre-schoolers are taught to count to 100, foreign languages are taught starting in the 3rd grade. My grandson was proficient in speaking Japanese in the 5th grade and he is now into Mandarin Chinese in the 10th grade. Science and Engineering also are accelerated from when you were in school. So, if you are doubtful, take some time away from PPRuNe and discover what is happening in education today, it isn't the same as when you were 13 years old.
