      FAQs

      The Dual Program is for a period of 11 months. You are expected to devote 10 hours a week for lectures and around 3-4 hours a week for self learning and projects.

      The lectures are scheduled either early morning or evening, to suit students who are studying in college or are working professionals.

      We do not guarantee placements. Placement guarantees tend to limit student interest and their ability to work hard and compete. Vacancies for Data Science and AI specialists are available in large numbers in India. We are confident that we should be able to place all our students in good companies with high salaries, provided they are able to prove their competency through hard work and academic performance.

      We do not offer study loans, but we have tied up with banks who offer study loans are competitive interest rates. We help you connect with the lenders for the study loan you wish to borrow.

      Our US faculty comprises Professors who have taught students of multicultural and multi-ethnic backgrounds. They understand the challenges faced by students from vernacular backgrounds in countries like India. In addition to the US faculty, we have Indian Teaching Assistants who will help you resolve your doubts and concepts in Hindi and Indian English. There is no need to worry.
