For professional resumes, especially for people who have substantial experience like yourself, work experience should come first followed by a mention of your higher-end qualifications (graduate level and up - Bachelors onwards). Extracurriculars are important for MBA. So, that definitely will take the last slot in your resume. Another very important section is that of Awards & Achievements. This allows you to provide a snapshot of your major achievements in terms of work, academics, and extracurricular. You should quantify these wherever possible. Your achievements might get lost in the shuffle if you include them within your job description. So, consider this section seriously.
If you have the space and relevant points, then you can also consider something like Positions of Responsibility (outside work to showcase your all-round leadership skills), Training/Certifications/Professional Affiliations, and Community Service.
If space is too much of a constraint, I would suggest going with Work Ex, Education, Awards & Achievements, and ECA.
Hope this helps.
