There is a fanfic titled 'Harry's Elective Surprises'. In it, Harry is influenced by Hermione to take electives that are not commonly chosen by most students. This leads to some interesting encounters with new professors and spells that he wouldn't have otherwise experienced. It's a great read for those who like to see Harry in new and different academic situations.
One popular 'harry takes different electives fanfic' could be 'Elective Adventures of Harry'. In this fic, Harry decides to take some really unique electives like Ancient Runes and Muggle Studies at the same time. It shows his struggle to balance the workload but also his eagerness to learn different aspects of the wizarding world.
A third plotline could be that Harry's choice of electives attracts the attention of a new and mysterious teacher. This teacher has their own agenda and uses Harry's interest in the electives to manipulate him into doing things that may or may not be in his best interest. It could lead to a lot of self - discovery for Harry as he tries to figure out the teacher's true motives while also enjoying his electives.
He might take classes like Ancient Runes or Care of Magical Creatures instead of the usual ones.
It could be that Dumbledore has some strategic or protective reasons. Maybe the electives Harry chose initially could expose him to greater risks or prevent him from developing crucial skills needed later on.
Well, it might have a significant impact on Harry's academic progress and his future. For instance, it could affect his magical abilities and career choices later on. Also, it could cause tension or changes in his relationships with teachers and classmates.
Hermione could be with him. She would probably be there to offer moral support and maybe even use her vast knowledge to understand the blood test better.
One great 'Harry takes Ancient Runes' fanfic is 'The Runic Path'. In this fanfic, Harry discovers a hidden power within the Ancient Runes that helps him in his battle against Voldemort. It has a really interesting plot where he deciphers ancient prophecies written in runes.
Hermione would definitely be one of his top allies. With her intelligence and knowledge of the wizarding laws, she could help Harry in making important decisions regarding Ministry policies. Ron would also be there, providing his loyalty and courage in times of trouble.
In a 'James takes Harry' fanfic, the relationship between the two would be central. We could see James teaching Harry advanced magic that he didn't get to learn in the books. For example, James was known for being a talented wizard in his own right. He could introduce Harry to spells and magical concepts that are more advanced or even lost in the wizarding world. It would also be interesting to see how they interact with other characters. Would James be friends with the Weasleys? How would he handle Snape? There are so many possibilities to explore.
Obviously, Harry Potter is the main character as it's about him taking control. Hermione Granger is likely to be an important character as well, she would probably be by Harry's side, offering her intelligence and support.
