General feedback: Use a truth table to find the behavior of the circuit for every combination of inputs. Compare it to the truth table for the gates shown. Note that when the inputs to a NAND or a NOR are tied together, it works like a NOT gate.

General feedback: It helps to create a truth table with the output of each gate and go through one gate at a time until you come up with the correct values at the final gate. I would create a table with headings: A, B, U1A:Y, U2A:Y, U3A:Y, U4A:Y, U5A:Y and Q (U6A:Y). Note that in PSpice, Y denotes the output of each gate, whereas A, B and C denote inputs. I would then consider the outputs of these gates for all four possible combinations of A and B. (00,01,10,11)
