**Very important questions are bolded and may be asked based on this topic

PART-C

1.Compulsory Questions {a case study where the student will have to read and analyse the subject }
mostly asked from unit 4and 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   WhatsApp

Contact uS *These questions are expected for the exams This may or may not be asked for exams
    All the best.... from admin Santhosh

          Thanks for your love and support guys keep supporting and share let the Engineers know about Us and leave a comment below for better improvements 
If there is any doubt feel free to ask me I will clear if I can or-else I will say some solutions ..get me through WhatsApp for instant updates                                                      ~$tuff$£ctor
