    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.

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

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

their hearts show them the way.
