請問以下英文句子，應該如何翻譯，感謝。 Planning one day ahead has done as much to improve the grades of some students as memory or speed-reading courses.?

Planning one day ahead has done AS MUCH to improve the grades of some students AS memory or speed-reading courses.
= Planning one day ahead has done AS MUCH AS memory or speed-reading courses (have done) to improve the grades of some students.
= Planning one day ahead has improved the grades of some students, just as memory or speed-reading courses have.
前一天事先計劃，對於改善某些學生的成績，如同加強記憶或是速讀課程，一樣成效卓著。

[補充]
缺少前後文，無法得知，planning one day ahead，確切的意思，我覺得作者想說的是 "預習"。

例句:
I think he has done as much as anyone could expect a president to do to get a piece of legislation passed.
= I think he has done as much to get a piece of legislation passed as anyone could expect a president to do.
