New accessibility updates for Microsoft Certification exams

We fixed the comment problem!!! You should be able to leave comments on case study questions. Thanks for raising the issue so that we could quickly resolve it. I'm also working with the team on the font sizes of the headings so it's clear what is a Heading and what is Subheading visually. (I think that's what the first part of the comment above was referring to.) Keep sharing your feedback. That's the only way we get better!
