Begin with a seven-lane diagnostic
Take a short baseline across Hindi, English, Mathematics, History/Geography, Civics/Economics, Science and Bihar GK. Record the concept behind every wrong answer. Do not infer readiness from a generic reasoning score because reasoning is not a named section in the cited CSBC syllabus.
Use Class IX–X texts as the source of truth
Read the exact school-level chapter before using shortcuts or one-liners. Mathematics needs worked problems; Social Science and Science need concept recall plus application; Hindi and English need regular comprehension and grammar practice.
Current affairs must be date-stamped
Build a rolling notebook from official government, RBI, PIB, sports-body and Bihar-government sources. Retire facts that change, such as office-holders and policy rates, instead of memorising an undated static PDF.
Model papers are a review instrument
Use the 100-question original model in 120 minutes. After review, classify every loss as knowledge, reading, calculation or time-control. Re-study the linked subject band before the next paper; it is original practice, not a PYQ, and each released question has an individual evidence record.
Train for PET without mixing it into written marks
The main direct-recruit written stage is qualifying under the cited advertisements, while final merit for those lanes is tied to notified physical events. Begin safe, progressive fitness work early, but read the exact post/category rules before using any target table.
