This is BS. My good friend moved to California from Taiwan during high school. She struggled in all her classes (because she barely spoke english ("struggle" means she actually had to put in effort to get an "A")), but she excelled in math. She told me that she was an average student in Taiwan, but when she moved to the US, she suddenly became a math genius. She was in the highest level math class the school offered, and it was a breeze for her. So, nope, she didn't "drag down" the statistics - in fact, just the opposite.
