추가 적립 안내

압구정 현장 강의를 통해 Prealgebra부터 AP Calculus까지 가르치 면서, 강사로서 느낀 점은, 학부모님들이 선택할 수 있는 국내에서 판 매되는 전문 교재가 몇 개 없다는 것과 충분히 많은 연구와 노력을 통 해 개발된 교재들은 더더욱 부족하다는 점이었습니다.
국내 수능 시장에서는 "OOO" 커리큘럼으로 진행되는 수업들과 교재 들이 많은 데 비해, 미국 SAT 시장과 유학 시장은 그렇지 않았기 때 문에, 이렇게 유하림 커리큘럼의 시작을 알리는 것이 기대되면서도 떨립니다.
Prealgebra를 처음 배우는 학생들이 흥미롭게 배우길 희망하면서 교 재를 썼습니다. 또한, 강의나 교재가 너무 쉽다고 느껴지진 않을 정도 의 개념 강의 수준을 유지하기 위해 노력했으며, 지금까지 수업해왔 던 내용들을 많이 담았기 때문에 국내에서 유학을 준비하는 학생이나 해외에서 공부하고 있는 학생들에게 도움이 되길 진심으로 희망해봅니다.
