Online exams influence assessment by expanding access, flexibility, and speed. Secure platforms deliver varied formats, accessibility tools, and analytics that reveal learning gaps. Yet high stakes, technical glitches, and time pressure can elevate anxiety; some students even search phrases like hire someone to take my exam during stressful moments. Educators mitigate risks with authentic tasks, randomized banks, open-book designs, and clear rubrics. Practice runs, reliable networks, and responsive support reduce friction. When thoughtfully designed and transparently governed, online exams measure real skills, promote equity, scale efficiently, and uphold integrity across diverse education systems worldwide for students, educators, institutions, and policymakers.
