Do you think my college professor is being too lenient on students?

My final exam for Chemistry is next week. My professor told us that it will be comprehensive and cover the 7 chapters that we have learned in class. Out of nowhere, just today, he changed his mind so that the final exam will only cover 1 chapter. He said that other students were complaining that it's too hard for them to study everything, so he made it easier for them. I'm in the minority here and have studied all the chapters, so for him to change it at the last minute b/c of students' complaints seems too lenient for me.
