Submit random choices on Google form

I've written a Python script that randomly selects radio buttons for each question, and submits the google form. My main questions for improvement are:

• Algorithm: I collect all the buttons into a 2D array, then use random.choice to select the radio buttons based on each nested array. I'm sure there's a better way to do this, since my algorithm is basically hard coded.
• Performance: I know random.choice takes a lot more time than other methods, but it's the only way I know enough to write with it.
• Wait Time: Right now, I wait .75 seconds before entering in another form. I'm wondering if there's a way to wait for the page to load completely, rather than wait and hope that it loads fast enough to not generate a page not found error.

        buttons[random.choice(options[i])].click()

    driver.execute_script("window.history.go(-1)")

    #Output how many forms have been submitted thus far
