The challenges of reading and writing for students with dyslexia, and other learning differences such as dyspraxia and dysgraphia, can feel insurmountable.
You may perceive yourself as unable to keep up with your classmates, and not deserving of good results, as you do not know how to take in information or develop your answers on the page. You may not realise that these difficulties are aspects of your learning difference and not a fault of yours.
Students with dyslexia need more time to process the information they are receiving and may prefer alternative ways to access their learning and to produce their work. Once a dyslexic student is in secondary school, it is these frustrations that come to the fore, along with the challenges of poor working memory, (see Sascha's blog 'Study Tips For Dyslexic Students' for more on that issue).
