Btw DS didn't use a laptop in any lessons, or GCSE or A levels, not until degree level when they all use them, but he had his dictaphone to use in the lectures etc
In senior school very helpful to get printout of whiteboard notes, the teacher just needs to click print and it will print off the notes on whiteboard, so no hassle during the lesson and a highlighter pen
Yes touch typing would be a good idea as they can then type while looking at the whiteboard
IMHO and IME you really need a proper diagnosis and report from properly qualified ed psych
The report completely amazed us as it had him on or near 98th percentile for most of it but processing speed was on 7th percentile along with a couple of other speed related tests, I transferred the results into a bar graph to show to DS and my goodness it was very obvious
Please don't be frightened of helping your child reach their full potential
Kind of look at it like, your child is really good at running but his shoes are too small that they hurt his feet so he can't run as fast as his potential allows, so do you buy him new shoes that are bigger and will help him reach his potential or do you leave him in the small shoes?
All you are doing by asking for an ed psych assessment is taking them to have their feet measured to see if new shoes would help
If new shoes aren't needed then fine but if they are needed then also fine, get them and watch him run as fast as he can to his full potential 


DS has had 2 assessments through his school times, one in primary, then another aged about 14
The teenage one took less time to conduct but iirc he needed it to qualify for the extra time in GCSE etc
It doesn't go on his medical records and it was up to him if he told the university as it didn't automatically follow him from senior school
It is our job as parents to tell schools things about our child but at University it is completely up to the child/young adult to decide who knows what about them so please don't worry about the "label" following them without their consent
Please ask for help and an assessment from ed psych, good luck
