Latisha’s goal is to climb the corporate ladder in her organization. she just earned a bachelor’s degree in business administration, and she wants to update her résumé by adding her degree as well as the last two positions that she held before her current position. what type of résumé format is the best for latisha?

I suppose the following points that you should added in your resume:
1.The basic information about your name, age, and the place that you graduated or where do you come from etc.
2.The bachelor’s degree, because it can demonstrated the knowledge you have learned.
3.Because you are already in the company, so I think the, if the  the last two positions is in the same company, than you can added in the resume and explainthe achievement that you have made, if not, do not added in your resume.
4.You can also add some awards that you have made before.
5.The last part, I suppose that you should add some Professional title certificate to show your storng skill, or you can make a short introduction about your personality.
