I purchased this from shachihoko@Please read profile, but I have passed my first-choice medical school and finished my exams, so I am selling it. I purchased it as data, but I only have a copy now, so I am selling that. Quote: This is an original compilation of standard methods and ways of thinking for frequently tested areas of mathematics in entrance exams. I have achieved results in many math mock exams and contests, such as a Tosho Mock Exam math deviation score of 92, passing the Math Olympics preliminary round, and winning an award in Gakkon. In the process, I researched many mock exams and problems, and this is a compilation of the fundamental principles and standard methods that were commonly seen in many problems. Although it is 26 pages long, each standard method is very important, so I think it has tremendous value. Areas covered: 1. Combinations and Probability 2. Geometry ① 3. Vectors ① 4. Vectors ② 5. Geometry ② 6. Geometry ③ 7. Trigonometric Functions 8. Calculus 9. Sequences 10.
