Hello!
I wonder with scores you will be able to fetch a decent college or university. I would advise you to take up a second chance and look with universities that take up their own entrance exams. You need not to worry at all, JEE is not just the final destination it is just the pathway. You can have a look over other options to get into engineering. You made me recall my days, I too had almost similar situation. I have done my engineering from Lovely Professional University. Have a look over Lovely Professional University. Few of the major features that make LPU stand high from others are :
#the highest Number of Placements in Top MNCs (Microsoft, Amazon, Cognizant, IBM, etc. )
#the highest Number of In-house Industry-Sponsored Labs for Hands-on Exposure (Microsoft Innovation Centre, SAP, Oracle, IBM Software Lab, Virtusa Robotics & Automation Center, HP Center of Excellence & many more)
#Guidance by Professionally Trained Faculty & Industry Experts via use of the latest Teaching Aids and Live Projects
#Flexible Academic Model with Choice Based Credit System
#Industry-led Course Curriculum designed after taking inputs from industry experts and academic leaders, and match the standards defined by national and international accreditation bodies
#Research, Innovation & Industrial Consultancy as a part of the curriculum
#400+ Research Publications in Reputed Journals/Conferences
#Regular Workshops & Seminars by the Industry Experts
#Dedicated Technical Clubs to enhance practical knowledge of the students
#Well Qualified and experienced faculty members. #National and international Accreditation with ranking among Top Universities by NIRF. Also at LPU you need not to worry about Fees structure, LPU offers huge scholarships as well and most important there is no donation at all. The better you perform, the better scholarship you can get. One Tip: Apply soon to grab the maximum scholarship. There is lot more at LPU. I hope this helps. All the Best!

Civil is more of a core branch while design is not. It completely depends on your interests as to decide where you should go. Institutes do matter but branch matters a lot more.
Quality of teaching: I can tell you that civil department professors at IIT-Bhubaneswar are quite good. Although I don't know much about the professors at IIT-Guwahati but still, IIT-Guwahati being older will be equally good if not better.
Campus life: IIT-Guwahati has a much better campus life than IIT-Bhubaneswar, so there will be much better exposure. But newer IITs are improving at a fast rate. There will be fewer students in IIT-Bhubaneswar compared to IIT-Guwahati so there are better opportunities for an individual to actively participate in extra academics activities like societies and fests. Although sports facilities at IIT Guwahati are much better than IIT-Bhubaneswar.
Placements: IIT-Guwahati design will be mostly offering non-core placements while at IIT-Bhubaneswar you have a much better chance to get core placements (this year more than 70 percent students got core placements). So, if you have more interest in the technical stuff then I would suggest IIT-Bhubaneswar civil as a better choice over IIT-Guwahati design. The average package for IIT-Guwahati design will be greater than IIT-Bhubaneswar's civil branch.
