What this is not
It is not the Class 11 syllabus compressed into Class 9. It is the Class 11 syllabus started in Class 9, at a pace a fourteen-year-old can actually absorb, with the school board work still coming first. By the end of Class 9 a student on this plan has covered a substantial part of Class 11 Physics and Chemistry and the Class 11 maths toolkit — not all of it, and I would be lying if I said otherwise.
It is also not for every child. It needs a student who is comfortable in their school syllabus, who is genuinely interested, and who has four to six hours a week to give to this on top of school. If any of those three is missing, the honest answer is to do the school year well and start in Class 10 or Class 11. I would rather say that on the phone than take the fees.
Which board does this suit?
All of them, with one note. CBSE students have the smoothest run, because NCERT is the line JEE and NEET are written on. ICSE students carry an advantage in numerical work and a disadvantage in a few NCERT-specific topics, which we cover separately. SSC students need a little more English-medium technical vocabulary early on. IGCSE and MYP students usually need the most computation drilling and the least conceptual help.
The board pages are here: CBSE Class 9, ICSE Class 9, SSC Class 9, IGCSE, IB MYP. The year ahead is Class 10 Foundation.
