Here's how the big English tests compare:

• IELTS- Paper test, speaking with examiner, popular for UK/Canada

• TOEFL - Computer test, American English, preferred by US universities

• PTE - Fully computer-graded, fastest results (2 days), accepted in Australia

PTE is the newest and quickest, while IELTS and TOEFL are more widely accepted. Your choice depends on which country's universities you're applying to.
