I need to take the IELTS for college, but my first language is English and I speak it fluently. Do I need to study for it? My English score on the SAT is 650.

Yes, most top-ranking universities in the US and the UK require both an SAT score and an IELTS or TOEFL score. The SAT demonstrates your academic proficiency, while the IELTS or TOEFL assesses your English language skills and your ability to use the language effectively in that region.
