 Okay. Okay. Hello, everyone. Please type in your name, Shreya. Pull out there, please tell me. Shreya, what have we done last class? Can you tell me?

Jeldal method, Sridev, it is there in practical chemistry. Okay, we'll do it. But not today. It's just, you know, method to determine the amount of nitrogen present in a given sample of organic compound. Okay. Just the application of mole concept calculation we have to do according to that only. We'll do this in practical chemistry. Practical chemistry is not there in JEE main syllabus. It's probably there in advance. But we'll do this. There are three, four methods for the determination of nitrogen, sulfur, phosphorus and all. So we'll do this in practical chemistry, not today, today. Okay, they have done hydrocarbons. GOC, they have finished, right? Ionic equilibrium, have they finished? Ionic equilibrium? Okay. So we'll do this hydrocarbons, GOC, which is left. We'll do this in physical class. Okay. Your test is over, right? School test. Can you tell me where the next or is the unit is left or you are left with only the final exam? Okay, it's coming in January. Can you see the screen now? Is the screen is visible? You can't see the screen. What is visible? Is it something like Centrum Academy logo is there? Only that one is visible. Yeah, I think there is a network problem. Okay, I'm not in Bangalore right now. I'm at my hometown. So I'm in my hometown. That's why some network problem is there. Okay, so I don't think you are able to see the screen like this because the net is not working properly here, I think. Anyways, we can do one thing. Can you share your Skype ID if you have?
