PART-C
1.Compulsory Questions {a case study where the student will have to read and analyse the subject }
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
*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 ~$tuff$£ctorSYllabuS
