hello i read the other guy's post "Do you think this guy in Iran would be name a genius if he was in USA or first world?" and two questions came to my mind, "why nearly everybody tries to relate success in science to IQ while there are people that don't have high Iq and they are success in science?",and "if there is God why there is such a difference between high and low Iq people?" I myself live in Iran and have an Iq of about 105 and it has been proved in several internet based or paper based tests,but i got my Bs in mechanical engineering from Amirkabir university,the third rank university of iran(after Sharif and Tehhran universities),and got my Msc from Sharif university of technology(it is the best university of Iran in most engineering fields and it is called as "MIT of Iran"), as you see i don't have a high Iq and i am not one those rich people that they go every where due to their much money (as the other guy mentioned i took Konkoor too),i finished my Bs and my Msc as 5th rank in Amirkabir and Sharif and without no doubt students that are in Sharif and Amirkabir mechanical engineering are among the most genius people of Iran(my personal experience has shown me at least 90 percent of them have Iqs of +130 and most of them +140) and i was an exception between them for having a low Iq, so i have been successful in my education but still there is one thing that really sucks,despite my good scores in final exams and despite a lot of try that i put on my projects because i didn't have a sharp mind i was criticized with some of my professors that "your place is not here,you should go to somewhere it's people are as intelligent as you" and in labs i couldn't finish the experiments as fast as other students and nearly in everything that had a little and limited time to do it like one hour labs(everytime in labs the professors came and gave a little and short explanation of the experiment,after their explanation other students started to do the experiment and they really did it good and fast but i really got confused and even didn't know where to start and while other students were finishing the experiment i was just in middle of it!) or pop quizzes i really sucked and i really had big fears and stresses from these time-limited subjects!and it really was a very bad experience for me to see "why they can and i can't", now because of lots of pressure and stress i had during my education i have really lost my belief to God, so if there is God why there is such a difference between high and low Iq people?
