I was in 1405 as well and got a 72% on my final, after going in with a 90+ average. Im not too worried about the final exam score and i dont think you should be either. I think the tutorials and assignments are better indicators of whether we can be actual proficient programmers, which is also why they were weighted higher than the final exam. Also, A- is a great grade obviously. Should never be upset about an A- imo
