I am very pleased to share with you what Khan Academy had done for me. I started to take my GED at the age of 43 in September 2017, and refreshing math and science at this age was not an easy task. Thanks to Khan Academy I was able to pass my GED all 5 topics by the first time. I would also like to mention that since I am a technical instructor, my education will be like energy conversion which my students will also benefit from a better instructor and all this education makes a better world.
Thanks for your good work
