PIP, Cerebral palsy and processing of information, stamina and fatigue

PIP reading and budgeting question.
If you can read, but have limited reading stamina due to CP and processing what you have read, would you be likely to score 2 points?
I get fatigued easily and having to concentrate makes fatigue even quicker. If I'm reading something  I often have to re read several sections again because it has all gone in. (Not sure if it's part of CP and/dyslexia.    The fatigue , processingand stamina have been major issues during my education years, for which I had a SEN, 50% extra time in exam and several multiple extensions to complete assignments. I also have some issues with maths  so I cannot do mental arithmetic and even with it written down would take significantly longer.  I find it very hard to hold numbers in my head and do sums.  I know £1 minus 50, but if you told me to mentally add up 1.59+ 1.37+ 2.98, I wouldn't be able to do this and would take me a long time written down. Will this count?  Thank you. Also, how many others with CP have these problems?
