Below is a brief list of material science teachers in Bangladesh on various platforms. I have attempted to provide the names of teachers who have their own channels with plenty of free content, so that a student can click on the image of a teacher and visit their YouTube channel for assistance. Another important point I want to make clear is that I haven't prioritized or categorized teachers based on their familiarity, seniority, or any other criteria. Everyone listed here is considered best, and I haven't engaged in any verification or selection process. I've simply listed the names as they came to mind. Hopefully, no one will have any issues with the order of names being mentioned first or last. There are many other teachers who conduct paid classes on various platforms and do not have much free content on their own channels; I haven't included their names in the list. However, if there are any teachers who provide sufficient free content but have been omitted, please email me (providing name, picture, and YouTube channel link) because there are many others like me who are unaware of them. I request everyone's assistance. Additionally, if you have any comments or complaints about any topic, you can email me first.
