marked questions on real oat

hi,

i took a practice oat on the kaplan website and i marked questions in the nat science section. i got to the end and then clicked on the button to go back through all the marked questions, but it only let me go back to the o-chem problems. on the real test, once i get to the end of all three nat science subsections, can't i go back through all 3 of them to finish my marked questions?
