16d. "It helps to raise the water level if food has run out (7)." I have S-A-o-F, but am not sure of the O (see below).
24a. "I'm left struggling over an exam until the very last moment? (3, 3, 4)." I think this is FOR ALL TIME, the "FOR" giving the O in 16d, but I can't understand the wordplay if so.
