The process of subjects of choice requires several things needed to be done:

• Teacher offer
• Data entry about past subjects of choice
• Student offer
• Calculation of groups
• Making notice about given subjects of choice
• Students are sent a notice, so they can enter their wishes about subjects of choice.

After entering data about student´s choices, we start calculating subjects of choice.

After the program is finished with calculations, we make a notice for students about their subjects of choice.
