sir we get questions
when we get modul Question papers
Model paper of 2022 scheme pls 🙏
Sir it’s really helpful to us thank you very much u reduce the student burden in wasting a time with searching papers and nodes thank you so much ☺️
Pls share the model paper with solutions
It’s my belief that mesothelioma is usually the most deadly cancer. It’s got unusual traits. The more I look at it the more I am confident it does not react like a true solid tissues cancer. When mesothelioma is really a rogue viral infection, so there is the probability of developing a vaccine plus offering vaccination for asbestos exposed people who are open to high risk of developing potential asbestos connected malignancies. Thanks for expressing your ideas for this important health issue.
Sir we need model question paper
Please share model question paper
U uploaded dco question bank in OS section where OS question bank went..?
Please share solved model paper which is present in vtu website.
