Thanks for the responses. With me its a case of sitting down and sifting through large volumes of textual information that intimidates me. Generally my reading is OK, its just that I concentrate on the word themselves as opposed to the meaning of the words, which for obvious reasons will slow one down. As studying for an ATPL requires you to digest large quantities of information over a relatively short period of time I think this is an area that I could slip up on. As for my spelling, its probably on par with a 10 year old.
I think the physical act of flying an airplane is unaffected, although I do tend to find difficulties when using the clock face to get a bearing on another airplane or reference point. I don’t have any problems with left or right though
