Indigo review after 3 months

As mentioned I have been at Indigo for 3 months, almost 4. I think they attempt to be theme driven and give us news articles but the essays that they write don't feel like something I can write during my exam. Giving us the sample essays are also quite confusing for me because I feel the need to be the same but often I cannot and I feel like I lose my personal voice trying. Their examples are also very lengthy and I definitely cannot be memorising all of these. Any more balanced lessons offered by other centres?
