I started to use Blender last week, so I'm kinda new here. I was wondering if someone could check the lighting in my house model? I believe that is what is causing all of my grainy and low quality renders. I have tried many solutions such as increasing the resolution to 100%, enabling Multiple Importance Sampling, using regular Path Tracing with square samples instead of Branched Path Tracing, and messing around with the Render Tab settings. I'm still trying to figure out why my animation is taking more than 8 hours to render a simple three second video and why it is so blurry. My windows laptop has an NVIDIA GT 520M, 8GB of ram, and a 64-bit operating system. This is for an important school project and it weight 98% of my grade. I hope someone can help:)

The final render is too grainy and poor quality.
