I had a very lacklustre time in school. I would sometimes do well with new subjects but lost interest, daydreamed and played up.<br>At age 11 I took the English 11plus IQ test and won a place at a Grammar School much to the surprise of many. <br>Then I reverted to my old ways. <br>But at age 16 we were all given IQ tests as a part of choosing subjects to A level and with an eye on careers.<br>Again, my careers teacher (who also taught economics) expressed surprise, telling me I had scored in the top 0.5% of the population (later confirmed at 154 when tested again age 27 by my employer).<br>So, having spent most of my schooling thinking I was stupid turns out that I wasn't challenged and was just bored and distracted.<br>Must happen to many kids.
