Many ESL Youtube channels are really designed for more advanced students, which is part of what makes Learn English with Jennifer (or Jennifer ESL) such a unique channel. Jennifer is a calm and organized teacher and most of her videos are perfect for beginning students. She even has videos on the English alphabet.
Of course, if you are looking for something a little more challenging, she also has a video series on academic English, as well as one on pronunciation. Since her channel has been in operation for few years, she has many resources available for online students.
