Can your forms grade?

For example:  I want a to be graded but where there isn't one right answer. Like, if you picked mostly "A"s, you might be a Virgo.

Also, if that is the case - then is there a way to automatically send a response based on what someone scored?

I believe what you are trying to accomplish is possible with the help of the Form Calculation widget and by setting calculation values to the field question options.

Here's a sample form: https://form.jotform.com/80374971667974

In the Form Calculation's widget equation, I have used the avg() math function.

Based on the average, you can determine a value using conditions.

As for sending your respondents an email that contains their score, you can set up and email autoresponder in your form — Setting-Up-an-Autoresponder-Email
