Hi Mika! I think this is a very good strategy. Focusing on understanding the key concept from the reading and identifying the important details from the audio is essential to give a clear and complete answer in Speaking Task 4. Using phrases like “According to the reading…” or “An example mentioned in the audio is…” helps you keep a logical structure, which is excellent. As a recommendation, you could practice with real TOEFL practice audios and time your responses using a 60-second timer. This will help you improve your fluency, organization, and time management. You're definitely on the right track!
