I only use slader when doing my precalculus homework
Wow, sounds neat. Does that tool assist you with your homework?
Yes it can if you're clueless about how to do precal education homework.
It is good you found a way to get help with your school work. You should make sure that you understand it yourself though. You might not have the slate in your life all of the time.
It's fine since my parents are paying for my education and I don't care what they think.
Just because your parents are paying, doesn't mean you are allowed to slack off. While it's wonderful you have a tool to help you outside of school, your education really matters for the future. So how about try using the tool, and then reinforce it through study groups or asking the teacher?
