Questions & Answers about O campeão tem impressionado todos com o quão rápido memoriza.

Could I use como instead of o quão to say 'how fast' here?

No. The word como translates to 'how' when you mean the way something is done. Because you are expressing a degree (how much or to what extent), you must use o quão or quão before the adjective or adverb.

Is the o before quão mandatory in this sentence?

It is not strictly mandatory, but it is highly preferred. Adding the definite article o turns the clause into a noun phrase, which flows much more naturally after a preposition like com. Native speakers almost always prefer com o quão over com quão.

Why is the adjective rápido used to describe how he memorizes, rather than the adverb rapidamente?

In everyday Portuguese, it is extremely common to drop the -mente suffix and use the masculine singular form of an adjective as an adverb of manner. Saying o quão rápido sounds punchier and more natural here than o quão rapidamente, though both are grammatically correct.

Does tem impressionado mean he impressed them once, or is it an ongoing thing?

It is ongoing. The Portuguese compound past tense, formed with ter and a past participle, is used specifically for actions that started in the past and repeat or continue into the present. It implies he has been continually impressing everyone lately, not just in a single instance.
