some videos did'nt work in module 5 - random selection - interviews . the clips opened and played for a few second then stopped. attempted to play again but would'nt restart the video.

very good, alot of text - more animation would be helpful to explain definitions.

overall very very good. thank you.

very good course!

good

PICO question was too sensitive to punctuation and spelling.

Appropriate

modulo 2 es pésimo, debería ser con opciones y no para llenar, porque no es objetivo

I am finding the test section of the Cochrane course to be quite frustrating. When I get a question wrong that has four parts, I don't know which parts I've gotten wrong. When it tells me to go back to the specified section, I can't find the information that tells me what the answer should be. This means I end up guessing over and over to just get the question right so I can move on. I feel this isn't effective for my learning and means I don't actually learn from my mistakes during the quizzes. It would be better to just have one question per question rather than multiple choice questions within one single question, and/or giving more feedback and guidance on why the answers were wrong.
Additionally, I'm finding that when I put in an answer, sometimes it will say its correct and other times it will say its incorrect. So I keep redoing and redoing the quiz, then when I put in my initial answer, it eventually comes up as correct. This is also incredibly frustrating as I keep trying to find out what I did wrong (as above), only to realise my first attempt was correct after all.
Some of the sections are also difficult to read. I really like having the examples but I feel that these could be utilised a lot more during the course so that each concept is really clear and understandable in the context of an actual review. Especially the analysing the data section - having an example for each type of analysis rather than a few of them would be helpful.
Otherwise I am really enjoying the course, but just finding those above aspects difficult and frustrating to get through.
