i everyone, quick question regarding the sentence below.

Experts suggest that, while preparing for the GMAT, one spend as much time on brushing up the fundamentals as on mastering the advanced concepts, to avoid any surprises in the end.

Is the placement of the comma after "concepts" correct? I believe there should be no comma. In fact, comma makes this sentence incorrect by making it a run-on sentence. This is, however, the correct choice in the Aristotle SC study guide.

Please advise.

Thanks.

Curious to understand why do say that the presence of comma in this sentence makes it run-on?

because isn't "to avoid.." part an adverb that modifies "mastering"? I just think that adding a comma seems to turn it into an independent sentence but without a conjunction, which makes it a run-on sentence.

Actually a run-on sentence would be wrong even without a comma. So, comma is not really the culprit in such cases.

If this is still not clear, let us know which are the two Independent clauses that you think are being connected by a comma in this sentence.
