as a non-engineer i was in the same boat, and pyqs + strict timing helped more than any theory-heavy book. i kept a hit-list of topics i’d skip (p&c, probability) and focused on accuracy in comprehension, basic arithmetic, ratios, and data interpretation. also, random distractions were a real issue for me; during prep i kept getting dragged into junk tabs such ashttps://funkytimeonline.org/,https://crazytimeonline.org/,https://boom-city.org/and it messed with consistency until i blocked them. aim for 35-40 safe attempts with high accuracy and you’ll clear the 66 comfortably.
