you should prob get tested, It wouldnt hurt, I didnt get tested untill uni and although I had developed coping techniques with out my tutors knowing I was dsylexic I would have gotten deducted as much as 20% for the mistakes in spelling and gramma, I also struggle to write down exactly what I want to say...
How ever once you have been tested and have been diognosed if that whats you are then you then have to cope with being labled as a dsylxic person, which at times can be difficult and sometimes used as an excuse for being lazy, well in me anyway!
but now I have to tell my employers I am dsylxic but I tend to tick the box that says I do not concider my self to have a disability because it doesnt stop me doing day to day things...
Are you at school/ college? ask your tutors if they have noticed signs you could be dsylexic, however there are so many different signs diffrent to each person! Sorry if this is confusing.....
but yeah get the tests done, they are quite fun but some are challanging!
