Firstly, disclaimer – I know nothing about this matter; and not a teacher or educationalist. Have had friends who are dyslexic, but that is as much as I know on the matter, and I know that with dyslexia, as with everything else in the real world, no two people are the same.

I assume you have gone through all the usual channels with the dyslexia?

Don't know if there are any local support groups on dyslexia that might be able to help with strategies for dealing with the issues arising from dyslexia.

I assume her problem is with reading in general, and ofcourse most exams require a significant amount of very accurate reading. Maths particularly, you scan a line, and overlook a single variable in an equation, and you can easily get an erroneous result, even if you know all the theory behind it.

I suppose it should also be all the more important for her to develop the habit to check the reasonableness of her answers. For instance, (a very very simplistic example) if you multiply two number of two digits each, you would expect an answer of around 4 digits, and if the answer you get is of a different scale then you probably missed something somewhere; or if you add two even numbers, you expect the answer to be even, and if it is not, something is wrong. As I said, the real world is more complex than that, but if you know roughly what the answer you want should look like, and the answer you get is different to that, then work back and see where is started diverging from expectations.

Besides that, many many moons ago, when I was taking exams (in the UK, and in a very different system to that in place at present), I used to say I could get 50% marks by just guessing what answer the examiner wanted, without knowing anything about the subject – it's about the psychology of the exam, what sounds like the kind of question, and the kind of answer, that the examination is likely to to ask. Must admit, it sometimes caused problems in class, as I got lazy about learning the proper way of working things out when I could just guess what sounded like a reasonable answer to the question. But the point is that even if you guess the answer, you still have to work back and make sure that the answer does actually match up to the question (again, back to checking the reasonableness of the answer).
