I'm Now at 12th,I would like to pursue Btech Automobile but I'm weak in maths,so its possible for me.
If you have interest in Automobile engineering you should go for it. If you are weak in Maths you can improve it by lot of practice. It's totally depends on you.
All the Best!!
I think if you are really interested in Automobile Engineering then you should go for it.
If you think you are weak in Mathematics then you will have to practice it thoroughly and you will make it.
All the best!
