Hi, I am neither a teacher nor a professional, but happened to self-learn and pass this exam.
Your Bach Fugue is a 5-voice one if my memory serves me correctly. You are brave to take the challenge.
I am not sure if you are going to play all the repeats of Beethoven PS No 7. It is possible that the examiner may stop you to repeat in the section 1st movement, if he/she considers it's long. If you are not going to repeat at all, then you are perhaps playing considerably slower as compared to most players, and that's may not be good to the examiner if he/she is piano major.
Time, therefore, is a bit tricky. I supposed that you have started these pieces, and that you are going to take the 2014 examination. If I were you, I would not make repeats (except D.S./D.C.) in Beethoven PS No 7, and would find another short piece (in your case, no more baroque, no more classical, any thing romantic & beyond (excl. Chopin) for this 4th piece) to make up the time.
Good luck.
