Well to be honest, this is the biggest problem in my life at the moment. And problems could be much worse. But basicaly at the beggining of the year i was getting 90s and then there were concepts i didnt understand and i asked for help and the teacher helped me. But i still didnt understand the concepts and what u learn builds from the other units. Like, we need to know unit three to understand unit four. We are on unit five and i dont get unit one. Im more lost than the crackheads im getting 50s now. I really dont want to stick around and deal with the failure and shame of all this.
