You and Peter are working hard to prepare better for your college exams...

Over the next three months, you devote most of your time to college studies. You attend all lectures and never skip a class in college. You often visit the school library. You diligently fulfill the assignments of college teachers regarding extra-lecture work. Peter regularly helps you master topics that are difficult for you in textbooks. You realize that without Peter's help, your grades in college would have been much worse.

So, you have managed to increase your chances of passing the exams. It is likely that you will not be expelled from college.

However, a new problem has arisen for you. Moreover, this problem is extremely serious. The essence of this problem is money...

One day Peter was discussing studying for college exams with you.

He mentioned the following unpleasant fact: “By the way, I recently spoke with some of the employees of the administration of our college... Unfortunately, each of these employees confirmed the sad information for all students that tuition fees at our college will be significantly increased.. That is, both you and I, will have to pay in advance a much larger sum of money for education in the next academic year... Of course, we will pass the exams... We will prepare well for these exams... But we may be expelled from college simply because we did not pay the tuition fees in full..."

You are frustrated by this problem. You understand that the risk of your expulsion due to non-payment of tuition fees is really high. After all, your financial capabilities are very modest... It was not easy for you to collect the required amount of money to pay for college, even for the current academic year... But if college tuition fees are sharply increased next year... Then you definitely won’t be able to find that much money... And you will be expelled from college even if you got the highest marks in the exam...

You sadly ask Peter, "What should we do, Peter? Are we just going to give up and make all our efforts pointless!?"

Peter thoughtfully answers you: “Of course, I agree with you, Billy... We are not going to give up. Let those greedy college administrators raise tuition... Anyway, I will figure out how we can deal with this problem... Let's talk more about that tomorrow, Billy... In the meantime, let's continue to work on current assignments, preparing for lectures and preparing for exams..."

You nod. You and Peter continue to systematically prepare for difficult tests. You have almost no free time left. You feel very tired when night time comes. You go to bed and you fall asleep almost immediately. Your sleep is deep and you do not see any dreams...
