IDK-Yet was created to democratize access to higher education information for high school students by building an ecosystem that enables them to approach the future with confidence and ease. Our application focuses on helping students identify the academic pathways that best match their profiles. Our solution offers personalized guidance, powered by technology and enriched with carefully curated resources, designed to support the work of guidance counselors and education professionals. Today, new programs, and even new universities, are emerging at an unprecedented pace. Amid this abundance of opportunities, it has become increasingly difficult for students to determine which institution and course are truly the right fit.” Our response is to centralize everything: we bring together data from universities and academic programs worldwide through our proprietary matrix. Using a quick, personalized questionnaire, we gain insight into each student’s aspirations and then connect them with the programs and institutions that truly align with their goals. In short, IDK-Yet aims to turn an ocean of information into a clear, guided pathway, helping every student to go from β€œIDK-Yet” to β€œNow I Know”.
