minors, for whom there are no grade requirements.
You have also heard through the grapevine that it is sufficient to win a Fields Medal or Turing Award (regardless of what the ad may say).
Express the above as one PC wff.

Consider the wffs 
φ1 ≡ p1 ∨ ¬p2 ∨ p3 ∨ p4
φ2 ≡ ¬p2 → p3
φ3 ≡ p1 → p3
φ4 ≡ p3 → (p2 ∨ p4)
φ5 ≡ p3 → p4
φ6 ≡ p3 ∨ ¬p4
φ7 ≡ p4
