I think education is invaluable. It seems to me that you should not think about money. Education is necessary for everyone no matter how much it costs. I recommend you to hurry with the end of your study and have time for this summer school. And I advise you not to worry about the money spent, for example, that I spend a lot of money to buy assistance from the research proposal writing service ............... because I want to have good grades in order to then enter the master's program and then have a job where I will have a high salary. But not falling into such a program does not matter because the price is high and you can find a replacement for this school for that price! Therefore, I do not advise you to get upset if you do not get on such a program.
