JSS Polytechnic For The Physically Handicapped (JSSPDA)

No, colleges such as JSS Academy of Technical Education, Galgotias University, Kamla Nehru Institute of Technology (KNIT), Institute of Engineering and Technology (IET), and Harcourt Butler Technical University (HBTU) are not a part of the Joint Seat Allocation Authority JoSAA counselling process. JoSAA is a centralized counselling process for admission to Indian Institutes of Technology (IITs), National Institutes of Technology (NITs), Indian Institute of Information Technology (IIITs), and other Government Funded Technical Institutions (GFTIs). However, these colleges may have their own admission processes and counselling procedures. It is best to check the websites of these colleges or contact their admission offices directly to know more about their admission processes.

Based on your KCET rank of 12829, it may be difficult to secure admission in JSS College for CSE Engineering as the competition is high for this programme. However, the cutoff may vary each year, and it's difficult to predict your chances of admission without knowing the previous year's cutoffs and the number of available seats. I suggest you visit the official website of JSS Science and Technology University or contact their admission cell to get detailed information about the admission process and cutoffs for the CSE programme. They can provide you with accurate and up-to-date information and help you understand your chances of admission.
