Hi Shyam,

Remote area is no bar for a chartered accountant aspirant. And you have a pretty decent marks in 10+2 . And let me tell you your CA preparation and 12th class has a wide gap. There is no similarity between both. CA is a course which requires consistent preparation and focus. All you need to do is to register yourself for ca foundation online from the office website of institue of chartered accountancy of india which is : icai.org.in . Next you need to clear your foundation exams. And then you are into the CA course. You can then start preparing for next levels like intermediate etc. So to start with get yourself registered and start preparing with the books that will be provided by you by icai.

Good luck
