Select Academy and train the AI. Do not upload a single image within one frame, as the AI might misrecognize it. This could result in not getting the maximum number of stars. Based on my experience, out of 50 images, 5 failed to be recognized by the AI. So it's better to search for the image and take a direct screenshot. Use that screenshot for uploading. This way, your chances of earning the maximum stars will be higher.
