Should I Get a BBA at 40 and Aim for MNC Jobs Overseas With 15+ Years Work Experience in Data?

Hi sir, I have a few questions regarding the graduation program. I am currently working as a Data Analyst and have an undergraduate background (10+3 - Diploma in Civil Engineering) with over 15 years of work experience in various industries and roles. I am planning to join a BBA course that aligns with my work profile. The reasons for this decision are as follows: 1. Many MNC companies have made it mandatory for candidates to have a minimum of 15 years of education. While I understand that companies have their criteria, it is disappointing that extensive work experience is often overlooked in favor of a graduation certificate, which nowadays can sometimes be easily obtained without real merit. 2. A graduation degree is also essential for overseas job opportunities, and it has been my dream to work abroad for 3-5 years. Considering the above reasons, I have decided to pursue a BBA course. However, I am facing some challenges: a. Having completed my studies in 2008, I am out of touch with academic pursuits and have concentration issues, which may make it difficult for me to pass exams. Nonetheless, I understand that I need to overcome this and focus on my studies to achieve my dream. b. I have two options for the BBA course: online mode and distance education (offline mode). I am unsure which mode will better support my goal of securing a job in an MNC or an overseas opportunity. c. My close circle has suggested IGNOU University, stating that its certificate has a good reputation in the market. Therefore, I am uncertain whether to choose an online mode (such as SRM Institute) or an offline mode (such as IGNOU or KSOU University). Could you please guide me on this matter? Thank you.
