As following the correct order of the lessons is very important for their understanding, I advise you to refer to the Course Order before making your selection. Similar to your studies at school or any other tuition class, please ensure that you are equipped with necessary stationery material before commencement of the lesson. I advise you to sit and listen carefully to each lesson video and take notes as being instructed.

For some lessons’ questions, you will require to download certain tutorials from this portal as being guided and sometimes you will require to note down the questions forwarded by me in the video. After writing down the question, you should pause the video and try to solve the question on your own, taking enough time as you require. Afterwards, resume the video and learn and understand the correct steps and/or any mistakes of your own solution or your attempt to answer.
