Studied using the Dauntless software.....First four questions I never saw, two on GPS approaches, 2 on icing.
Used the Sportys E6B on a flight plan time calculation (winds, leg length, etc...), came out to 37.2. Two choices closest were 37 and 39. Chose 37 and it was wrong.
Missed the to / from triangle on another HSI one and pooched that question
Scored 78, DPE didn't care, never brought it up
Do all the non calculation questions first. Not that 2 hours isn't way more than enough time, it just gets them out of the way
