[Mr Rogers]

What does dissecting a frog or cat REALLY teach me about biology?

Answer - not much. And I majored in Biology in college.

Don’t recruits take the ASVAB anymore?

Dissecting a frog or a cat (1) reinforces what was taught in the lecture part of the course (2) gives valuable insights into a future human anatomy course.

I am glad you majored in Biology in college, there's no more exciting science than Biology. That's why I got my Ph.D. in Biology, I love it! But, back to your question, as a college instructor I can tell you there's a tremendous difference between students who had proper labs in high school and those who didn't. The former have an easier time and, on the average, seem to score higher on tests. That's my observation, not an opinion.
