Questions
Is safety training given before machine tests?
Yes. Correct use of starters, rating of meters and safe switching are explained before each test.
Will the lab file be checked?
Yes. Observation tables, graphs and results are checked for every experiment.
Is this course based on the BTEUP syllabus?
Yes. The units follow the BTEUP (Board of Technical Education, Uttar Pradesh) diploma syllabus. If your polytechnic follows a different board or a revised scheme, the centre teaches your own syllabus.
