PART-C
1.Compulsory Questions {a case study where the student will have to read and analyse the subject }
mostly asked from unit 5(OR) a situation given and you have to answer on your own
don't waste my hardwork and valuable time
As Engineer i think you know how to respect another
Share it as link alone . don't share it as screenshot or any text material if u found this anywhere kindly report me . #Admin WhatsAppContact uS
