PSEB

I am afraid not, because Canada looks at nothing less than 75% overall and 75% in Maths. So at least for all the top notch colleges it would be hard to get through if one does not score required percentage.
However, there is a way out. Incase one does not fulfill the eligibility criteria, one can chose diploma/pathway program to enter.
Idea of the pathway program is that one gets to study foundation program and does not get admission in degree program directly. However, after completing one year of foundation program, one can tranfer the credits into the degree program.

Yes, you can do correspondence course BA from IGNOU. It is a university for distance and correspondence courses. All types of courses are available here. You can opt for any course which you want to pursue. The fee structure for BA course is around INR. 7,000 - INR. 7,500 for the whole UG course of BA.

No, you have to take entrance exam to take admission in CCA. So, you are not eligible for the same.
Good luck.

If you are a general category student then definitely no. However, there a little chance of getting admission in AIHM Chandigarh if you're an SC/ST/OBC category student. The cutoff is usually high for AIHM Chandigarh. So my answer is no.
