I keep getting confused between many of the different verb conjugations.
e.g. ils pourront, ils pouvaient, ils puissant, ils pourraient (future, imperfect, subjunctive and conditional, respectively)
What tips do you guys have for remembering which is which?
The only tip is to learn them by heart, after having read some basic rules. http://french.about.com/library/verb/bl-verbconjugator.htm
And for your information, the subjunctive/conditional is "ils puissent"
