GMAT Sentence Correction (SC) | Re: Due to Vs Because of

here is another method that I use
suppose you have a sentence structure, e.g., XXXXXXXXXXXXXXX because of/due to YYYYYYYYYYYYY
now, if XXXXXXXXXXX can stand as a clause (complete sentence) on itself then because of is the correct usage; otherwise, if XXXXXXXXXXX is just a noun phrase then due to is the correct usage.
