The British drop their T's. Americans stretch their vowels. Both speak faster than any course prepares you for. And neither of them waits.
That's not a problem to work around. That's exactly what we practice.
I'm a native English speaker — born and raised across both the UK and the USA. In every 1-on-1 session, you get the real thing. The pace. The slang. The rhythm. The shortcuts that native speakers use without even thinking. British or American — or both. Because real fluency doesn't stop at one border.
Most tutors slow things down so you feel comfortable. I don't. Comfort isn't the goal. Fluency is. And fluency only comes from practicing at the speed you'll actually need.
