When you apply for jobs off-campus, then the companies pay very little heed to what your past academics are, especially of class Xth as it is a very far criteria. But this is only valid if you are very good at what you do, which in this case is coding.

So, if you think that you have exceptional coding skills and can crack the coding rounds of the companies that you are applying for, then there won't be any problems in any kind of placement, and you can get a job in even the top companies.

Hope I have answered your question. All the best!
