I have been working on the complaints that you lodged and I have come up with three solutions. I will resend all the notes from the first class of the first week. Though you can download only one of the following options:
Option 1: Lesson note and Voice note
Here you will have the explanation in seperate to the note. That is you will first copy the note and then listen to the voice note separately. The file will be tagged …Lnote and …Vnote
Option 2: Audionote
Here the audio is embedded inside the lesson note. All you have to do is click on the audio icon on the screen. When the audio stops, you scroll down to the next slide for the other part. The file is tagged … Audio note
Option 3: Video note
Here the audio is not only embedded in the note but the lesson is delivered like a real live class only that the teacher will not be seen. Here the mouse move on the screen for illustration, the pages change themselves to the end of the file and more user friendly. The file is tagged …Video note.
