Can it be interchangeable?

J'ai pédalé dans la choucroute est un expression tres droll.  J'aime beaucoup. Vous auriez dû le mention dans the leçon.

I'm very confused with devoir and which tense to use now, as your lesson said devoir in imperfect meant "supposed to do" and perfect meant "had to do", yet you use the imperfect to say "had to do" here ? Can you please explain and also explain what that lesson actually means as it doesn't seem to be relevant?

What is the difference in usage with cependant, alors que, pourtant, et en revanche? 

Quick question please. Regarding par le with trains and par with planes, why would you not use par le planes but you would use le with trains?

Merci

In the last sentence, why is the verb form used, nous ne serons pas pris, instead of, nous ne prendrons pas. I'm not sure what this verb tense is.

As 'secondary (or high) school' covers student ages from 12-13 to 18-19, it is not a simple choice between 'lycée' and 'collége' in my part of the world. It may be better to give an age range clue for the students if looking for a specific French level of schooling to be given, as there is no uniform standard in English.

For this statement: "Est-ce ta trousse? - Oui, c'est la mienne."

Why are we using "c'est" if it is about a specific item (the pencil case). In the previous lesson, if we know exactly what we're talking about we should use il/elle. 

Thanks
