Everything you need to speak french is in those classes, vocabulary, verbes, grammary, rules ... so I want to say yes, also learning a language isn't just about learning it's also about practice, as you probably know the best school to learn is to moove in a french speaking country, I know its often not possible. I propose private conversation classes and also group conversation classes to help you practice the conversation part.

Practice every day is the key, use diverse way, listen to audio, podcast, video, moovie, music... Conversation it's of course better to do it with someone but you can also talk by yourself, at the end of the day say out loud what you have done, liked, ate, did ... as you are getting better you'll see it will take you longer to do it and you can see the differences from the beginning.
What i find also really usefull, is to learn 5-10 new vocabulary word per day, at some point you'll know the grammary, how to create sentences questions negation... but if you have no vocabulary you'll always talk about the same topics.

Writing part help to remember more, it's also good because you have time to think and to use the right word the write temps.

First of all the classes are all explain on a pdf , and there is a video in english and in french with explanation for every topics we will see. If there si something that you don't understand of course you can contact me and I'll be happy to explain you what needs to be explained :)

Videos are all in english AND in french. This way when you are beginner you can understand with the english part and practice your listening with the french part, as you learn you'll be abble to switch language and use french most of the time and only use english if there is something you don't understand.
