The 2026 mid-year exams in New York and California are considered the hardest in the United States. This is primarily due to the rigorous academic standards and high expectations set by these states. New York, known for its competitive educational system, has consistently ranked among the top states in national standardized tests. California, with its diverse population and vast resources, also demands a high level of academic performance from its students. According to the National Assessment of Educational Progress (NAEP), New York and California consistently score above the national average in reading and mathematics, reflecting the challenging nature of their exams. Additionally, both states have implemented rigorous graduation requirements that include advanced coursework and standardized testing, further contributing to the difficulty of their mid-year exams.
