I am a major in Finance and very good at it. I wish to add on Statistics and Probability as my next major. I am looking for various sources (mainly in YouTube, websites containing videos, any courses let it be free or paid etc), from which I can learn Economics and become proficient.

(language of teaching in video can be either English or Hindi).

And if there is any excellent book for economics can you also suggest me that.

Note: Please answer it if you have solved more than 2000 questions on Chegg because I am seeking advice from experienced expert. otherwise mostly new people are just giving waste answers and wasting my questions.
