Congrats my students

CONGRATULATIONS ALL THIRD SEMESTER “ A” SECTION STUDENTS!!
I am happy to congratulate all Third Semester students , Particularly “A” section students who have passed in KINEMATICS OF MACHINERY and pulled up the Pass percentage of the second year of Mechanical Engg. The pass percentage in Kinematics of Machinery ME 2203 is the highest in all the theory subjects of second year. Cheers again…
Students who are not successful may try again with efforts.
