I have looked through all the lessons (level 1/2/3) and am unable to find the lessons where conditional is covered for present and past and there doesn't seem to be any lessons on plus-que-parfait (pluparfait). The only lesson I found was 19.6, which actually states that is was already covered and this lesson will be a review of sorts. Can anyone point me in the right direction please.
19.6 Imperfect and Conditional Tenses
In today's lesson we're actually going to go back to look at something we have already covered – the imperfect and the conditional tenses.
