    Many students are now facing with problems like deciding whether to focus on science or art.

Not taking the children's interest or preferences in account, some parents force their children to

make the choice as their will, that troubles many students.

     Throughout our lives we have to make much choices. As students, we should talk to our parents

or teachers especial on life-changing decisions. But when it came down to it, we're the ones who

must live with their choices. On the other hand, parents should try to help their children make the

best possible decisions, instead forcing them to do something that against their will.

     It depends on students themselves whether they'll be science students and arts students. Just let

their hearts show them the way.
