Mandatory Tour to reach 4th year College

Hello I am from Bicol University College of Social Sciences and Philosophy currently taking a 4-year Social Work course. I am now in my 3rd year and in order for us to move on to the next level, we need to join the mandatory tour this summer. The cost will be around Php15,000-20,000 per student and I really need help. My family still needs to pay for my tuition for next sem as well as the mandatory summer class with the tour and the expenses for our thesis. I have 3 younger siblings I don't want to burden my parents. I want to work part time but our schedule is very tight. Please help us. Any amount will do. Thank you.
