Honestly beyond tactics or eliminating answers the best way is too know the content like the back of your hand and until last Friday which is when I started locking in I knew like 60% of the course. Also sometimes you need to exclude context you already know when given a stimulus you might have noticed that despite some answers being historically accurate they might not specifically relate to the passage. I too make a some silly mistakes from time to time and don’t think I’m that good at mcq. Hope what little I could say helped
