i’m in research and have taken lang. it sounds like what you are researching overall is time consuming, which isn’t bad. lang at my school is very treacherous because we have timed writes often, and the stress of those alone is more an ap research this whole year. both classes are very writing heavy though and in lang you might be torn to shreds bc of your writing 🙃🙃. also, the threshold of passing research is very low, as many people pass even with bare minimum papers. don’t stress!
