My sister recently graduated from CGC Landran and has better information about the teaching techniques employed at the institute. Here is what she had to say.
In the first year of college, the teachers do not use projectors a lot and they just give the students notes for the subjects.
In the second year, the syllabus starts getting tougher and the length of the chapters in subjects also increases as the core subjects get included. It becomes a challenge to complete the syllabus in time. That is the reason why second year onwards teachers mostly give notes and teach from PPT Slides to cover up the syllabus.
Hope this clears your doubt.
