I have been in CS line for more than 3 years now, though as a student(currently doing B.Tech - CSE). I achieved 100% grades in CS in my high school. I will teach you basics (from scratch or your level) and how to code, visualize and approach a problem and practically demonstrate most of them in your preferred language out of the mentioned ones. Feel free to contact for doubt sessions as well. After all, now a teacher was once a student so do give me a chance and attend the demo class for free!! + more - less
