The shape of your weak spots
Every logged miss lands on a grid of question type against difficulty. The dark squares are where your points are going.
Where your misses cluster
Log every wrong answer, watch the pattern surface, and see how everyone else answered the same question.
You finish a section, see minus seven, and move on. Three weeks later you miss the same flaw question wearing a different costume, and you have no way of knowing it was the same mistake, because nothing wrote it down.

Where your misses cluster
The trap you fell for shows up next to the one most people fell for. Sometimes you were nearly alone. Sometimes half the room went with you.
What everyone picked
Your pick (D) is highlighted.
Every question gets its own thread, tied to the PrepTest, section, and number. Ask why C beats D and get an answer from someone who just sat with the same passage.
PT 141, Section 2, Question 19
PrepTest, section, question number, what you picked, what was right. Add the question type and how hard it felt. If you just finished a section, tick the wrong ones in a grid and fill in the details after.
Your score line, your goal line, and a grid of where the misses actually cluster. You stop guessing what to drill next, because the heavy squares tell you.
See the split on every answer choice, then read what other people said. Being wrong in a crowd is a different problem from being wrong alone, and the fix is different too.
