"just like"

Hi,

How I would put it is that while it is awkward and I cannot remember a question that used it, "just like" shall never be a deal-breaker among the answer choices. The answer choices would generally test a more fundamental rule in the question and your eyes need to be elsewhere, on that more fundamental difference. Else, there is no end to such list of nuanced differences and trsut me, GMAT doesn't expect you to remember all.

Focus on the eight main rules together with the meaning. These alone (and only these) can get you to a high accuracy on GMAT SC.

All the best!
