<human>: Can you condense the text into three sentences or less?

So my parents have been in complete control of my finances (I don't have access to my credit cards/bank accounts/etc.) my entire life. I know now that that's not a good thing, but I didn't feel like I could question it because they were paying for college (and my expenses). Soon I will be going to grad school and earning a real salary (previously earning ~$5k a year, all paychecks handed straight to my parents to help with college costs) and paying things for myself, other than remaining on their health insurance.

I will be making ~$28k/year as a grad student (expecting a much higher-paying career long-term), with rent $500/mo and food/home expenses ~$200/mo. To my knowledge, there is no debt in my name, my credit card is on a shared line with my dad, and I have some small amount of savings/bonds/funds connected to my mom's account.

As someone who has zero experience or knowledge about finance--what do I need to ask them? What are the most important financial things to know? What things should I have access to, and what is the best way for me to save? Should I split savings between long-term and emergency, and how much?
<bot>: What questions do I need to ask my parents when I take back control of my finances, and what should I do with the answers?
