 many things which I had not known before. So actually, I'm very, very happy that whatever I've learned here, I'll be able to apply to my students. And my students will also be very, very happy for this. And they're going to learn practical physics. We used to teach physics, now they're going to learn physics using practical methods. So would you say this course has helped you? Yeah, very much. And now I am able to deliver my students because I have so much years to use. Yeah, so it has helped me a lot. And I appreciate it. But of course, the experiments we're doing, the practicals we're doing, were nice and loud. And get results.
