This is a great goal! Instead of setting a range, I’d pick one percentage to make it clearer. So something like this:

“I will understand 50% of Tuesday staff meetings and podcasts by June 30”

It’s good you’ve committed to 9 tutoring sessions. Have you scheduled them yet?

Are you able to record staff meetings? Or note down words you hear repeated often during the meeting?

For listening comprehension, I recommend reviewing words using flash
cards with audio (you can use an app like Quizlet). The podcast is
great because you can repeat the section you’re having trouble
understanding and use it as a source of vocabulary.

I give more about how to approach listening comprehension goals in episode 51: https://www.learnspanishconsalsa.com/51/
