सवाल
Which chapters are covered?
All 9 chapters of the current NCERT rationalised Class 11 Chemistry syllabus, followed by CBSE and UP Board.
How is organic chemistry taught?
Step by step: IUPAC naming, then reaction mechanisms, then reactions of hydrocarbons, with daily naming and reaction practice.
Do you cover numericals?
Yes. Mole concept, thermodynamics and equilibrium numericals are practised with solved examples and NCERT exercises.
Is there a test series?
Yes. Chapter tests, monthly tests and a full-syllabus final exam with explanations of every answer.
