Here is what I do:

In preamble.sty

    \boolean{ExamWithSolutions}

In exam comment/uncomment

    \setboolean{ExamWithSolutions}{true}

and then

    "problem statement"

and then

    \ifthenelse{\boolean{ExamWithSolutions}}{"Solution" here}{Else}

By the way, I am using the above within probsoln—which I like very 
much—with Else = "multiple choices" so that I can print a "BlueBook 
Question", "BlueBook Question With Solution" and "Multiple-Choice Question".
