Mom has no logic

My mom wants me to do a math website called IXL. So basicly I have to do six IXL topics If I don't finsh I can't go to sleep :(. When I ask for help and she say wait then she says she tired so I am stuck at an IXL topic with no help at all. When I do a topic say I am at 99 points if you get it wrong it puts you about 92 then another one wrong it's 82 then it keeps going down till your at a point that you give up. Then there is my brother when my mom tells him to do IXL my mom babysits him until he gets all the problems right or he just sits watch things on the IPad doing nothing but playing all day. So I am writing this about 10:05 PM looking for some help. Sigh ...

But the thing is I don't know how to do the problems and she yells at me for not knowing them.
