Content creation

I am new using H5P.  I have created my training content, adding questions throughout my class for students to answer.  I need all the questions points to join and give a total score for the class. ( I hope this makes sense)   I don't know how to get it to work.  Any help?

Hi all.  I'm using the drag and drop with images, but the images come out squashed.

Does anyone know what size the images should be?

Also, how do I add a question 2 in a Multiple Choice quiz?  I only see Add Option and don't see where to add next question! 

thank in advance
