Hama Gakuen Grade 4 Math - Highest Level Math Problem Set, Answer Key & Supplementary Text Volumes 1-4 Review Tests & Calculation Tests with Answers & Answer Sheets All 42 sessions Thank you for viewing. This is a full set of Hama Gakuen Grade 4 Highest Level Math, excluding the calculation problem set. Since the Grade 4 Highest Level Math course was taken online, there are no names written on the materials. I erased some writing from the problem sets. (I apologize if I missed any.) Also, since I used the review tests by copying them for the online course, I checked them and they were in good condition. (I apologize if I missed anything here as well.) I used and disposed of only the calculation text, so I don't have it, but there are calculation tests, so I think you can do the highest level calculations. The tests are all complete from No. 1 to No. 42, including problems, answers, and explanations. (Please consider the tests as a bonus, as I am an amateur inspector and there may be errors.) The problem sets show signs of use. Some pages have folds. I think there will be no problem using them, so please consider the above points before purchasing. Shipping and handling fees apply. I do not offer discounts. I do not sell items separately as I want to sell the entire set. I also do not hold items. Thank you for your understanding.
