hello !! i'll add more later if you need anything else but for the speaking card, my teacher gave us an acronym ARSQ !!
answer the question in your answer to the speaking card, say if you agree or not etc
refer to the text, mention something in the text, a statistic, reword a statement in the text
structure - add a complex structure, maybe subjunctive, always have a subjunctive phrase template in the back of your head because i think it counts for slightly more if you use it during the conversation following the card
questions - just the questions you'll ask to the examinor
generally, aim for your answers to be about 3-4 sentences long, write in shorthand where you can to save time, don't write for the full 5 mins, the examinor might stop you if they think you're writing too much. during the test, make eye contact with the examinor (or just fake it and look in their direction, you get marks for engagement), don't look down at your paper too much. try to be as controlled as you can with your words, you are allowed time to think after examinors ask you a question in the conversation part, learn some phrases along the lines of "i have understood the question, i need a moment to think" or "good question, please let me think"
just realised that half of this only rlly applies to speaking cards where you get a photo but you have to write and answer a question thats based on the text and disregard the photo in your answer entirely. i have no idea if different exam boards have different cards but this is the advice/feedback i've been given !!!
