With test day nearing, I have encountered a new problem. On my latest mock exam, I would stare at a question which just would not compute. Some examples:
- DS; x^2-y^2=?, where 2xy=60. Spent 5 minutes looking for a way to reach (x+y)^2, and could not connect the dots. Guessed.
- DS; a(1+b)-c. "ab" and "a-c" were given. Spent 4 minutes on it without making the connection. Guessed.
- RC; could not absorb the passage at all. Inner voice telling me to abandon the passage ASAP ended up drowning out my attempts to read it. Got half the questions wrong (despite consistently getting 20-streaks of RC sets 100% correct)
Bizarrely, all of these happened in the second half of quant and the first half of verbal (Q-V-I test order). I had not a single mistake in the first half of quant, nor in the second half of verbal. During this period my mind just stopped working. Time management suffered, too.
For reference, I get Q50 every time, and have OG accuracies of RC 98%, SC 95%, CR 80%.
When I retried these questions a day later, I solved them instantly (these, plus two questions I had lost to time management). There were some CR questions that I absolutely did not understand even with the OE - but these are an acceptable loss. What's not an acceptable loss, though, is to make such preventable mistakes... and I worry this mechanism could repeat on test day. I took the mock at the same hour as my real exam. Does anyone know what the problem could be?
