Intelligence Status: Going down
The conflict of the story is that Charlie is mentally challenged, and he wants to become a genius. He sees all the people around him (besides the other adults in Miss Kinnian's class) and wants to be like them. This is why he tries to be the person to become smart in the experiment
After getting accepted as the person to become smart, Charlie writes more about his days before getting the procedure. The procedure is what is supposed to help him get smart. It works and he has to do things like look at dictionaries and listen to a tv that was provided to him. These allow him to learn more.
The climax is when Algernon and Charlie start to regress and get progressive amnesia. Charlie has to try and figure out why it is happening before it becomes to late. Algernon eventually stops eating and slows down before dying.
After Algernon dies Charlie doesn't want the doctors to dissect him and so he burries Algernon in the backyard. Charlie at this point is continuing to forget things and eventually gives up typing as his grammar gets worse and his ability to write becomes harder.
Writing one last letter to everyone he knew he is going to completely forget everything and decides to leave, not telling anyone where he's going. He knew he did something for science although he didn't know what. He doesn't want to live in a place where people knew he was smart once and pitied him. It made him feel bad and so he left, the book ending with his final letter to everyone and him asking for flowers to be put on Alernon's grave.
