  • 저기 저.. 죄송한데 test 2 questions 21~40 중 37번 정답은 D가 아니라 E인것같습니다. 수정 부탁드리겠습니다.

  • Hello, I just had a quick question for you about question #23 of Test 3. It's the question mentioned in 8강 video of the ACT Math. Instead of putting 1/2x for the capacity of the smaller bottle and leaving the capacity of the larger bottle to be x, can I do the opposite and double the capacity of the larger bottle to 2x?
