Kangaroo.Study's 2025 RMO R1 Detailed Solutions——First Release

The RMO Round 1 concluded yesterday. We promptly shared the answer key with everyone and conducted a detailed analysis session on YouTube in the evening. Additionally, our Kangaroo teachers worked through the night to compile a comprehensive summary and solutions for all the problems.  

After checking the answers, we believe you now have a preliminary sense of your performance. This year's exam included some challenging questions, but none fell outside the scope of our teaching materials—in fact, some were topics we had just covered. Feel free to review the problems, and even those who didn’t take the exam can give them a try. Detailed solutions are attached at the end.  

Compared to previous years, this year's RMO also showed some shifts in the exam trends, such as an increase in computational problems and the absence of geometry model questions. We will soon publish an updated RMO question pattern analysis, which we hope will be helpful for P4/P5 students.

Detailed solutions are provided below

We hope that through our sharing, everyone can learn from this exam, improve themselves, and strive for even better performance in upcoming exams such as APMOPS and NMOS (P5).

After next week’s APMOPS exam, we will also be sharing the actual questions and detailed solutions. You’re welcome to follow our YouTube channel in advance and join our study group to receive updates as soon as they’re available.

The teachers at Kangaroo.Study will continue to provide you with full support and assistance to help you achieve your ideal results!
