I believe the conflict here is Greg Heffley versus the world. I say this because of many of the following reasons. Greg always tries to impress another girl in and out of school. Unfortunately, it always takes a turn of events and doesn't go as he planned. Like the figure-skating rink for example, Greg wanted to talk to his crush and ask her to skate with him. But right then, the "Couples Skate" was over and he missed his chance. Greg hates school and because of it, he doesn't get good grades while in school. But the thing is, he doesn't care about it at all. This definitely shows this conflict because Greg basically wants to get the school into extinction. And in contrast, the world doesn't do that simple thing. Another example that shows the main conflict are the things his parents make him do and sign him in things that don't fit his life. The best part of it was going to Spag Union, a military school, during summer vacation. Like I said before, Greg hates school and this school is even worse than the one he is in right now. So, Greg tries some plans that make him not go to that school. All didn't go so well until the very end of the book. He didn't go to Spag Union after all, and so he celebrated his summer vacation like nothing else. The best overall example, though was Greg against his brother, Rodrick. Greg and Rodrick always fight alot, always get out of some new rules, and not work each other's thing out, etc. The 2 brothers do work together on some occasions, though. For things their parents say as the new rule, Rodrick always finds a way out of it and not Greg. Greg is maybe even more wimpy than Rodrick ever since day 1 (or book 1). Either than that, he has enemies at his school every day too. Most of it being Patti, which fortunately,doesn't appear in the book. This has been my description of the book's main conflict: Greg Heffley versus the world!!!!!
