Dear Priyanshu, CA itself is a professional course to start off. You haven't mentioned your highest qualification. You can start off as early as after your 12th to start studying to become a CA. Now previously there were Foundation, Intermediate and Final Courses. Now they have been changed to CPC, IPCC and Final Courses. Now CA Foundation course is also called as Common Proficiency Course. For being eligible for this course, you should have completed your 4 months of study period and then appear for CPC exam. These exams will be held in the month of May and November every year and for more information on important dates, eligibility and syllabus, please visit their official website at https://resource.cdn.icai.org/45555bos35643faq.pdf

Hello student there's only one course that is chartered accountants you need to pursue to become a CA.
There're 3steps 1)CPT which held in every November and may 2)IPCC 3)FINAL
Once you clear IPCC you need to do a article ship of 3years.
So basically the course duration is 5year almost.
