Maths Spl

Dear Yatharth, admission requirements are different for each university. Universities look beyond academics, however they will have their own norms. As an architecture applicant you must also submit a portfolio, let your creativity speak. University of Waterloo I think requires a science background but University of Toronto do not have such a requirement. I will advice you to email a few universities including the two I mentioned. Carleton University, McGill University and University Laval also offers b.arch.
Best wishes

U can do degree in electronic engineering with d certification

U can go for cs ,c.a,bms etc without maths u can do if u know only the basic calculations

If you want to choose an engineering branch solely on maths, then B. Tech in Mathematics and Computing from IIT Guwahati and IIT Kanpur could be a couple of options for you. However, all branches of engineering will have some subjects on Mathematics.

Bba colleges have entrance exams. You have to fill forms asap. Most are out. You can try symbiosis, narsi monji, op jindal. There are many. If you can prepare for entrance then try iim indore and CBS Delhi.
You will have to check how many are still open to take registration
