Hi Mariah! I am an MLT student who is planning to sit for the MLS exam after my MLT + experience (I have a B.Sc. already, so I also had/have the same questions. From everyone I've talked to, the biggest difference is that the material covered is the same, but MLS gets more technical and in-depth with the concepts, often elaborating on more niche information or special topics. For my program specifically, I've heard that people who got their MLT here and went on to an MLS bridge program really didn't learn anything "new", just more technical aspects or niche info. I hope that helps a little. I think focusing on more special topics or really understanding the intricacies and details of certain topics will be the biggest differences between the exams.
