Not really. Outliers of that sort get dealt with as an exceptional case and it works. I've seen amazingly bright batchmates get into all sorts of programs without most of the qualifications, because they were a genuine math wizard (the kind that submitted errata to a standard textbook on some weird number theory stuff at age 15), but they didn't always score the best on many exams, especially when aggregated across subjects. IIRC he's a researcher now. All trends point to him being an eccentric old hag at age 50 ;)

The filtering system is meant for the majority case and there it works. The outliers get dealt with as outliers, which also works. In this case, he later asked the author of that textbook who he emailed with the errata, to connect him with the group he wanted to work in. Needless to say it was a very strong referral.
