2 LessonsFrequently Asked Questions
Does this course follow the latest CBSE Class 12 CS syllabus?
Yes. It covers Computational Thinking and Programming-2 (functions, exception handling, file handling, stack), Computer Networks and Database Management (SQL and Python–MySQL). Extra NCERT chapters — queue, sorting, searching and understanding data — are included too.
Is the material copied from NCERT?
No. Every lesson is written originally by CodingEasily with new examples and diagrams. Use it with your NCERT textbook.
Are the program outputs real?
Yes. All Python programs were run on Python 3 and all SQL on a MySQL-compatible server; the outputs shown are exactly what was printed.
