I hope it goes well for you. However I have to agree that 128 may not be a good enough score in the current climate. (right time and place means an awful lot). If it isn't then give anything else your best shot.
In Part 2 the individual problem carries an awful lot of weight, so if your self analysis is OK, you should feel pleased with yourself.
This forum is full of all the people who like to moan (and they are entitled to if they want ), but in the end if you treat it as a job and career and accept that it may not be lifelong (except for the very few) then you could be very satisfied.
Good Luck, and well done for sharing your hopes and experiences.
