Chartered Accountant

Accountants of all types are responsible for the financial efficiency of a business or organisation. While having the same duties as other accountants, a chartered accountant (CA) has completed additional postgraduate education and a period of mentored work experience.
Chartered accountants offer financial advice, audit accounts and provide trustworthy information about financial records. This might involve financial reporting, taxation, auditing, forensic accounting, corporate finance, business recovery and insolvency, or accounting systems and processes.
The average salary package that fresh chartered accountants are today getting at entry level positions in major corporate houses is Rs. 7.36 lakh per annum.
Now, coming to your 2nd question on - CPT, IPCC.
There are four stages in Chartered Accountancy course.
CPT
IPCC
Article ship
CA Final
CPT which stands for Common Proficiency Test is the first stage in CA.
CPT exams are conducted twice in a year in June and December.
If you clear CPT then you can register for IPCC which is the second stage in CA course.
IPCC stands for Integrated Professional Competence Course.
If you are done with graduation then you can directly appear for IPCC through direct entry scheme. Direct entry scheme lets you appear directly for IPCC without appearing for CPT.
You should do article ship for 3 years once you are done with IPCC.
Then the last stage is CA Final. IPCC is the second stage whereas CPT is the foundation of this course I.e. it is the first stage in CA course.
I hope I have clear your doubts.
