If the first word feels too easy, it probably scores 10. We would type RF Engineering: Deep Cut, +85, 13 letters, about 4 seconds on a keyboard. Do not burn the 25 seconds on Aerospace Engineering, Chemical Engineering, Civil Engineering, or Electrical Engineering — those are Plankton. The trench answer is Explosives Engineering (+100), but only take it if you can spell it cold.
Trench spelling, only if you already know it: Explosives Engineering +100
