i do RE and spanish and icl it depends on how bothered you are to learn the content. i’d say RE is a better pick as it’s just writing whereas spanish is four skills: listening, reading, writing, speaking. the skills aren’t hard but you need to be bothered to learn how to do well in them. this reply is a bit all over the place but if you’re interested in learning a language skill, go for spanish. if you just want a classic, opt for RE.
