MD 100 test - Study help

Hello, my name is Richard and I am currently in training to become an IT-Konsult. I have been studying a lot regading the MD-100 now past month and have done 1 exam but failed with 684 points, 700 is minimum. I had a weakness regarding Install and configure Windows and the other was okay. I have been trying to find subject around that area based on the questions I got and I have not really found much to make me improve.

So that's why I am asking the community here for some help and tips on what to read/watch to improve in that area, but also in other areas. I am currently watching video's on CTB Nugget and reading some parts in microsoft learning area. 

Would you recommend other website or communies to learn more? I would gladly accept any tips and ideas.
