Благодаря за обратната връзка.

Бях проспал условието, че студент не може да получава социална стипендия когато income > wage.

Добавих го с оператор '|' в първото условие 100/100.

import java.util.Scanner;

public class W2_E7_Scholarship {
    public static void main(String[] args) {
        Scanner scanner = new Scanner(System.in);

        double income = Double.parseDouble(scanner.nextLine());
        double score = Double.parseDouble(scanner.nextLine());
        double wage = Double.parseDouble(scanner.nextLine());

        double social_scolar = wage * 0.35;
        double excel_solar = score * 25;

        if ((score >= 5.5) & ((social_scolar < excel_solar) | (income > wage))) {
            System.out.printf("You get a scholarship for excellent results %.0f BGN", Math.floor(excel_solar));
        } else if ((score >= 5.5) & (social_scolar >= excel_solar) | (income < wage) & (score > 4.5)) {
            System.out.printf("You get a Social scholarship %.0f BGN", Math.floor(social_scolar));
        } else {
            System.out.println("You cannot get a scholarship!");
        }
    }

}
