Welcome to PF;
You will get the best results from here by showing us your attempt - this allows us to target our help to where you actually need it so avoiding wasting time for both of us.
Your main problem is the need to have someone else verify your answers. This is a problem because you are supposed to be training to handle problems where nobody knows the answers - who will verify your answers then? You need a way to verify the answers for yourself - unless we know where you get stuck we cannot help you with that.
