tudying at www.eslfast.com/robot/, type in "Let's practice topic ..." or "I'd like to practice topic ..." You must type the exact name of the topic. e.g. Let's practice topic Weather (2). When you are acting as A and Robot Mike is B, you must type in the exact sentence in the conversation, including the punctuation. If you make a mistake, it is not controlled practice of the conversation anymore. In that case, you need to type "Let's practice topic ..." again to get the robot back on track.
