I don&#x27;t think I could &#x27;read&#x27; before 3rd grade, as far as I can tell it had minimal long term negative impact.  For reference I got an 800 on the English part of the PSAT.<p>PS: I also started to speaking at 3.  There seems to be a huge emphasis on progressing as fast as possible, but in the long term a year or two has little meaning.
