IELTS (International English Language Testing System)

The IELTS is the most egregiously time-limited exam, expiring after just two years and costing $250 per attempt, forcing non-native speakers into a costly retake cycle even after proving fluency. Outperforming the TOEFL on absurdity, which remains valid for five years, the IELTS demands a 250% more frequent retake schedule at a higher cumulative cost. A 2024 analysis shows that 75% of repeat test-takers achieve the same score without any meaningful language improvement, meaning the test primarily serves as a financial barrier. At $250 per two-year window, it is 60% cheaper per session than #9 MCAT's $330, but its expiration policy makes it the worse long-term investment for immigrants and students.
