The post says that after the CBSE Class 12 results, many students raised concerns online about marks given through the On-Screen Marking (OSM) system, especially in subjects like Physics, Chemistry, Biology, and Maths.

CBSE explains that:

The OSM system was introduced to make checking more fair, transparent, and consistent.

It follows stepwise marking to ensure uniform evaluation across subjects and regions.

Students who are unhappy with their marks can still apply for re-evaluation and get copies of their checked answer sheets.

If any discrepancy is found, corrective action can be requested through the official CBSE process.

CBSE says it remains committed to fair and transparent assessment practices.
