Congratulations on the 320. That's a strong score, and from what you wrote it's clear you put in serious, deliberate work to get there.

Building a consistent schedule, using the error log to actually understand your mistakes, and narrowing in on specific weaknesses for targeted practice — those are the pieces that produce real score gains. Plenty of students study hard without doing those three things, and the work doesn't translate. You did it the right way.

One note for anyone reading this and benchmarking themselves against your timeline. Two months to a 320 is achievable, but it depends heavily on starting point, daily study capacity, and how solid the underlying math and verbal foundations already are. Some students will need three or four months, some longer, and that is not a sign anything is wrong. Skill development is the right metric, not weeks elapsed.

Also worth saying: strong scores tend to come from exactly the kind of error analysis you described, not from doing more questions. When students plateau, the fix is almost always tightening the review process. Identifying whether each miss was a concept gap, a misread, a careless error, or a trap, then redoing the question from scratch later to confirm the fix stuck. That habit compounds over time.

Thanks for sharing your experience.
