both are English exams but simply the TOEFL is (American English ) and IELTS is (British English )

I passed Cambridge Exam, so if i wish to work abroad, this exam is very useful for me as it means that you can speak English and it also shows your level. This exam will be actual all my life, while Toefl is necessary if you wish to study either in America or Britain, as well as I understand, and it's actual only for 2 years.

TOEFL mean is English proficiency tests to study in Arerica. Cambridge exams mean is examination　in Cambidge.
