Exams at the USESO are rigorous and require extensive study. Preparation often involves a variety of resources, including textbooks, online materials, past exams, and practical experience. We hope for students to explore and figure out which resources best suit their needs. 


The USESO Syllabus contains a broad outline of subjects intended to guide study. It is important to note that concepts covered in exams may not be detailed in the syllabus.
