2.2.1 – Identification &

Action taken of the

learning levels of the

students for Slow

learners and Advanced

learners

2.2.1 The institution assesses the learning levels of the students and

organizes special Programmes for advanced learners and slow

learners.

A large number of students with different socio-economic and academic

background take admission in various disciplines. Keeping in mind the

diverse background of students, individual faculty members identify the

slow and advanced learners and provide necessary counselling including

extra remedial classes so that the slow learners can come at par with the

other classmates. As regards, the advanced learners, extra coaching and

guidance is provided so that they not only excel in their annual

examinations but also are able to compete for competitive examinations

including civil and professional services. Advance learners are also

offered scholarships, the amount of the scholarships depends upon the

students marks.

They also have opportunity like opting for the IAESTE program which

enables them to carry out their projects in reputed Industries/University

across the world. They also get an opportunity to go for Internships in

reputed industries within the country.

Further, the University has kept one extra hour from 3.30 pm to 4.30

pm during that time no classes are held but students are free to approach

any faculty for any type of assistance, academic or otherwise. Students

who do not perform well in the semester exams are made to attend

remedial classes during the summer vacations, where special care is given

to each student because of the small batch size.
