Just a quick comment: my practice is to explain to students both the pros and cons of extra time (brain turning to mush from exhaustion is why I very rarely recommend 100% extended for standardized testing), their own agency in advocating at every level of education and career, and, more importantly, explain how understanding your own learning profile and accommodations helps you to make informed decisions about school, career, and life choices that allow strengths to flourish and weaknesses not to be obstacles. This includes understanding that applying for a grad program or job where needed accommodations will change the essence of performance expectations may not be the best fit.
