I was just wondering... how should I prepare for the types of math problems in the "additional topics" portion of the Math GRE? Sadly, I have not taken any courses in topology, combinatorics, and probability/statistics

, but I have taken courses in Set Theory, Real Analysis, and Complex Variables. I feel comfortable with the rest of the material on the exam, but I'm just worried about these additional topics that I have no background in. If I were to just focus on the additional topics that I know (Set Theory, Real Analysis, and Complex Variables) and just... not focus on topology, combinatorics, and probability/statistics, how badly would it effect my score? Would it be worth teaching myself these topics? Any input would be greatly appreciated!
