Practical retake plan
Second-attempt pass rates are commonly reported around 60–70% for major state exams. This is general study guidance, not an official statistic.
A focused window of 2–4 weeks targeting only the sections you missed is usually enough — but re-book only when practice scores are consistently at or above the passing standard.
The retake is a separate charge from the first attempt. Confirm the amount before re-booking.
Your score notice states the earliest retake date and any attempt limits. Follow that document — it overrides any general guidance.
