[DoE] does not grant any recognition to any board." Only CBSE, ICSE/CISCE and NIOS are valid in Delhi; 12 named fake boards listed (none named exactly 'Delhi State Open School', but the same category of unrecognised entity)

NOTE – CRITICAL CAVEAT: Not a government-recognised boardUnlike Bihar (BBOSE), Chhattisgarh (CGSOS) or Jammu & Kashmir (JKSOS), the National Capital Territory of Delhi has NO legally constituted state open-school board. The Govt. of NCT of Delhi Directorate of Education has explicitly stated in writing that 'there is no state board of Government of Delhi' and that it 'does not grant any recognition to any board' beyond CBSE, ICSE/CISCE and NIOS. Numerous privately-operated websites (dsosboard.com, delhiopenschool.com, dsos.co.in, dsos-ac.in, dsos-co.net, diosonline.org, delhiboardofopenschooling.in, etc.) brand themselves as 'Delhi State Open School' / 'Delhi Board of Open Schooling' but are NOT government bodies — they function as private admission/study centres, typically reselling registration into the genuine National Institute of Open Schooling (NIOS), whose own Delhi Regional Centre serves this need legitimately.

NOTE – RecommendationFor legitimate Delhi-based open-schooling data, use NIOS (national board, Delhi Regional Centre) rather than 'DSOS'. The subject/marks table below is included only because it was explicitly requested, and reflects the SSC/HSC structure claimed by these private sites — which mirrors NIOS's own subject list almost exactly, since they operate as NIOS feeder/study centres. Treat as informational only, NOT as an independently verified government examination scheme.

NOTE – Data statusNo official government source exists to verify a distinct subject/marks scheme for 'DSOS'. Subjects below are reconstructed from the standard NIOS Secondary/Senior Secondary pattern that these private centres advertise.
