I have it in my notes that “après que” uses the indicative tense, so is there a reason why the subjunctive is used in this occasion ?

What is the meaning of grand-daughter in French?

Elle va acheter le poisson aujourd'hui du marché. Merci beaucoup.

This lesson has me scratching my head with the simple question - why is it here? One of the very few things I remember from O level french (failed) was that regular past participles form ER>é, IR>i and RE>u so to my way of thinking battre follows the regular rule. Maybe this is because french is taught differently in France than it was in England 40 years ago, I remember reading somewhere that the french don't have the same concept of group 3 (-RE) verbs but have several smaller groups including -DRE.

Il faut toujours essayer ... avant de juger. I used soi since I read this to be a universal self where soi is used. Why is it soi-même? What’s the rule to differentiate when using On to mean universal, we the people, etc? I used soi in a previous question using On and it was correct. Thanks. 

<< Vous les montrez à mon père et vous ________ ensuite. >>

The answer is : << me les montrez >>

Why isn't  << les montrez à moi >> allowed in this case?

Also, do the following sentences have the same meaning? Which sentence is incorrect? Why?

On fait du sport régulièrement, ce qui est important.

C'est important qu'on fasse du sport régulièrement.

C'est important ce qu'on fasse du sport régulièrement.
