Speaking is the most difficult when learning a language. Most of the people are better at reading, writing and listening than speaking. It can be because they have the wrong teacher and he or she only gives them papers to read and grammar exercises to do. Or it can be because you are naturally shy and maybe lack of confidence. Either way, this is your teacher's job to help you improve your speaking skills and this is where we shine.
If, because of the reasons above you don't want to go through grammar or tenses lessons again, that's okay with us. Our teachers are also available for speaking sessions. More than that, they are really good at boosting your confidence and finding interesting topics to discuss.
Brew your coffee and call your teacher while having breakfast! Simple as that.
