Since "win" and "victory" are synonymous, the term "win a victory" is just a more complex version of "winning".

This is my daily in Malawi.

There was chaos at Form 1 class today because the students registered are supposed to be 100. Indeed there were only 60 students in class today. Ten other students transferred because I think they are chosen by another school for being smart. Ten other students are absent. Perhaps, the other students cannot afford to go to school anymore

The government encourages the students in primary school to proceed to secondary school but some students cannot afford to pay school fees. Finally, they have to drop out of school. My co-worker said that next week would be the beginning of the second selection.

I think there will be more chaos because more new students might come. In that case, they might be confused again because they wouldn't know what to do. Others might be one absent from class. Most students are also very noisy in class.

Sometimes, I give them some class activity to work on, such as experiments while others copy notes.

Indeed: "Indeed" is used to confirm, and it has been misused here. "However" or "But" would be the proper word to use, since the sentence suggests a sudden switch, like a Plot twist.

Finally: "Finally" is used to signify that this example would be the last. "Unfortunately" would be the proper word to use in this sentence.
