We conduct Online courses on WHATSAPP, wherein the Lectures are shared through audio, video, text, ppt. etc. in a very simple yet efficient way. The student may be not be online at that time. As per his/her convenience he/she can read, download, understand and listen several times the lecture and ask doubts on whatsapp if any. Doubts are cleared before next lecture. We have weekly two days off on online classes wherein the subject taught in the entire week can be covered by the student is they didn't get time entire week. So working people can also get benefitted. Also on those weekly off, the trainer and students come online on same time to get their rest of the doubts cleared. Lot of Retired, Working and even students fraternity are getting benefitted of the online courses 
Check for Spandana Healing Astro Vastu Center Wagholi at JUST DIAL website for reviews of students done online training for feedback and confidence. You wont regret. That's my challenge
