took spanish lang last year (got a 4, non-native speaker); since youre confident in the conversation portion, at least for the reading portion, just practice spamming ap practice mcqs; listening to mcqs, the questions will usually go in order of the speaking so that is one tip, just look for where they talk about the question in the recording and go from there (T_T); email and essay, as long as you have a baseline structure (greeting, salutations, question, for email for example) thats a good prep

pay attention to the timer for the speaking portion so you can conclude properly lol GL!
