Hello Aspirant,
*Due to the COVID-19 different educational boards have reduced their syllabus by almost 30% at both the levels that are national as well as state level. Similarly Bihar board has also proposed a reduction in syllabus of class12th to the state government but till now the approval has not been given for reduction. So until and unless syllabus gets revised and released by the board we can only help you with previous year's syllabus to have a glimpses of 12th board syllabus.
