Excellent post from @ParmaVioletTea
OP, I hope DS was or will be present on the call.
@ParmaVioletTea and I are academics very much wishing the best for all students. Dare I say we both have a soft spot for the underdog.
With the best will in the world, there is only so much you as DS’ parent can and even should do. After all, in the bigger picture of his life university is not the end: you surely want for it to prepare him to move forward. For that to happen, he needs to thrive at least reasonably.
You haven’t given us a sense of the severity of DS’ autism and selective mutism, not that you owe us one. . But there is obvious potential for concern here: please see again the post from @ParmaVioletTea One wonders whether spending a year getting stronger and gaining practice negotiating the world before beginning university might benefit DS? Often universities are receptive to a request for a gap year for a student with special needs (or anyone else) when that year is presented with a structured plan geared to enhanced preparation for university.
Whether they have special needs or not, almost all students who take a structured gap year seem to benefit from it, and I write that from the perspective of a very demanding, high tariff School. There isn’t anything the least ‘weak’ about taking one.
Very best wishes to DS
