When it comes to your I.Q how big of a factor does memory play,and what about concentration? If you have an amazing memory and you can recall most of the information you previously learned with ease,then it will be really easy for you to do well on a test or tackle new concepts that are related to what you have all ready learned because you have built the base of that concept in your mind and it will be really easy to build up from there,especially if you have an amazing memory. And if you have the ability to stay concentrated for long periods of time without losing interest or focus combined with a great memory it will be easy for you to understand almost any concept with the right amount of time and work contributed to learning that concept. So what we call "I.Q" can really just be boiled down to having a great memory accompanied with a great concentration. I know there are things on I.Q tests that measure fluid intelligence like pattern recognition,but things like that can be learned with time. Just want peoples opinion on this subject. I know it's not well written,but i was in a hurry to write this. Thanks for reading.
