Which way will the equilibrium shift when subjected to the following changes? 2NOBr + heat <-> 2NO +Br2?
NO is addded
temp. doubled
Br2 removed
Pressure increased
I said: reverse, forward, forward, forward

Correct on a,b,c.
I don't know on D.
When pressure is increased the reaction shifts to the side with fewer GAS moles. You didn't write the phases. If Br2 is a liquid, increasing P will have no effect since there are 2 moles on each side; if Br2 is a gas, the rxn will shift to the left for increase in P (2 mols on left vs 3 on right).
