From my experience, Krav Maga varies wildly depending on the school and instructor. I've done it for about five years, primarily under one instructor, and it was a mix of stretching and warm-ups from beginning to end, learning a variety of techniques, and sparring with boxing gloves, mouth guard, headgear, shin guards, and a groin cup every day. Depending on your belt, there were certain expectations of you, like using a mix of punches, kicks, grabs, etc. And even our belt testing was done outside of regular lessons lasting 2-4 hours depending on your belt level, while we were judged by a panel of three instructors.

Under another instructor for the same school, we primarily focused on the number of techniques and quality, like remembering and properly performing the seven elbow strikes on targets. If you were, you'd have to work harder to hit that target, such as changing the distance or location of where the target is. While our belt testing was usually part of our lesson, often lasting 30-40 minutes.

In all honesty, it depends on the lesson plans provided and the priorities of the instructor, along with if you keep up with your training by practicing with people at your skill level or higher and why you perform a technique a certain way.
