I have been using TSTI for a few months now and it has exceeded my expectations. The website is easy to navigate and the lessons are comprehensive and well-explained. The incorporation of emojis in the materials adds a touch of creativity and keeps students interested. I have noticed a significant improvement in my students' understanding and retention of scientific concepts since using TSTI. I highly recommend this company to all science teachers. 👍
