If you compare ill and joe as far as scholarship
goes, you will have to conclude that ill is, without
any question, the brightest. are there mistakes in the previous sentence?

The ones that jump out at me relate to the fact that "ill" is kind of a funny name for a person. I'm thinking they must both be misprints for "Jill" or "Bill" or "Will".

I'll put in corrections I think should be there as bolded. If you do not agree, don't feel pressured to do exactly what I did! :)

If you compare Jill and Joe - as far as scholarship goes - you will have to conclude that Jill is, without question, the brightest.
