Answer 1

I found

http://www.geocities.com/~harveyh/magicstar_x.htm

about Magic Stars



He shows two order 7 Magic Stars with sums of 30.

I gather there are 70 others.



A web search on Magic Stars should turn up more information.

.

Answer 2

If the teacher doesn't say that you cannot repeat numbers, try this...

Put 15 on all of the tips of the star and 0 on all of the vertices inside the star.

First of all:

never use numbers higher then 24, cause if you use all different numbers in rows of 4, the lowest 3 are 1, 2, 3. with 24 left to make 30



apart from that I'm still guessing.



haha, I hope you can't use the method of the person above me, that would be too easy :-P
