Calculations are not right.  incorrect forward pass and backward pass. 

there are incorrect numbers.  On the first problem, the ES is incorrect for G – you must take the larger number on forward pass.  What is odd is that you got the late items correct via the backward pass.  On the second problem, you have similar mistakes.   double check the math I did please. need help figuring out both problems. recolor critical path on both please
