Hello Aspirant,

The eligibility norm for B.Tech lateral entry is as follows

• Aspirants should have accomplished 10+3 qualifying examinations or diplomas.

• Physics, Chemistry and Mathematics subjects are obligatory.

• Aspirants who are B.Sc graduates in Physics or Mathematics after 10+2 will also be assessed as desirable.

B.Tech lateral entry is the immediate access into the second year of B.E /B. Tech (third semester), after earning a diploma in engineering or B.Sc in Physics or Mathematics.

Approved learners don't study the first year of B.Tech and will be desirable for immediate admissions.

The course duration is six semesters (3 years).
