really really good courses thnks alot , i d download all of your videos on youtube , If I could pay, I would definitely do it, but unfortunately because I live in Iran and there are banking sanctions and the value of money here is very low, I can not help you financially, please continue recording videos because you are a good teacher and you provide well And the worst part is that I can not use your non-free courses in any way because there is no way to pay in Iran tnks dev.mojafari@gmail.com
