i am preparing for some banking exams,can u please suggest me some parallel course. .any field.

Every field has its own pattern of conducting exams & selection. If u r interested in preparing for banks ...do concentrate in tht only. All the Best ..!!!

Parallely you can opt for other distance courses as well, But your first focus should be on Banking exams.There is nothing wrong in doing other courses paralley and whole world is doing this.
