The IELTS (International English Language Testing System) exam has two types: the Academic and the General Training modules.
The Academic module is for those who plan to study in an English-speaking country or seek professional registration, while the General Training module is for those who wish to migrate to an English-speaking country or want to gain work experience in such a country.
Therefore, the type of IELTS exam you should take depends on your purpose for taking the test. If you are planning to study at a university or other higher education institution in an English-speaking country, then you should take the Academic module. If you plan to immigrate to an English-speaking country or seek employment there, then the General Training module is more suitable.
It's important to check with the organization or institution you are applying to for their specific IELTS requirements to ensure you take the correct module.
