This is absolutely true . The syllabus the year 2020-2021 has been reduced for CBSC as due to the pandemic situations.

Most the students are not able to attend the online lectures due to low data reception also it is difficult for the teachers to teach every concept through PDF and PPTs .

Some subjects need practical discussions too .
