Not paying college fees

Q: I went to a college in 2015 and for three months I missed payments to them. I want to pay it back now but I only want to pay for two months. Because the one month we did not do much work and they wasted my time. Can I pay for two months or do I have to pay for all three months? They have no record of it, and they are not asking. But I know that I missed three payments. Do I have to pay for it or must leave it?

Performing Salaah with a sweet taste in the mouth

Q: If your mucus/phlegm has become sweet because of something sweet you ate then will it be okay to pray in that condition? Like in Ramadan when everyone drinks milkshake and eats dates when they break their fast and then they just wash their mouth out with water and stand up for Maghrib Salah even though their mucus is still sweet and the back of their throat is still sweet. Sometimes your mucus remains pink even after you wash your mouth out. What happens if you swallow this pink mucus during salah? Is it sufficient to quickly rinse out your mouth with water before salah or should you wait until the sweet mucus goes away? Sometimes I only break fast with water then eat after I pray to avoid this problem. What is the best way to deal with this?
