We won't give you direct answers.
We will help you to find answers. That means we will help you to think of the answers. We will not post links to where you can find the answers on the Internet.
You will have to be willing to use search engines and your brain to figure things out.
If you want a topic explained in a different way from how it's presented in your textbook or lecture notes, we'll be happy to try to provide you with that different explanation.
All the help here is for free. While we don't insist that you thank us for our help, if you get impatient or upset with the help we provide, you run the risk of not getting any more help. If you're patient and understanding and make a good effort to really learn this stuff, you'll make some lifelong friends and some great career contacts.
