I am used to another English MOOCS .
These courses are arduos,boring,slow,above all the grammar videos are very long and the after exercises are difficult so we have not time to retain so many information.
IDEA (Pdfs with the lists of phrasal verbs,or expressions,,,)
To correct three students exercises is complicated we are not teachers .
IDEA (Not 3 )
The 4 courses are repetitive .
Some exercises are quite difficult to understand ,the ones that you have to change trhe words to change the meaning .
But anyway of course THANKS .I appreciate your work it must be hard to prepare a funny,serious English course
I have completed them and I have learnt a lot of vocabulary and new subjects.
