Albert Einstein havis grandan scion.

Would mi havis multan scion work?

I don't think so, because that would mean: "I had many knowledge". I think, that "Mi havis multe da scion" - "I had a lot of knowledge" might work.

I guess that makes sense. Mi komprenas gxin.

In fact, "mi havis multe da scio" (not scion, because you'll never use the accusative after "da") means the same as "mi havis multan scion".
