The problem is attached. I'm concerned with the second question.

2. Relevant equations

Black-box testing/Boundary value analysis.

3. The attempt at a solution

Firstly, am I correct in calculating 10^9 + 6 + 26 + 11 + 61 + 8 + 8 = 1000000120 number of possible inputs?

For the second part (which is what this thread is about), I watched this video:

but, I'm still confused as to how to do this particular problem.

I'm thinking that I need to make similar partitions and then use the boundaries of each partition which, in this case, consists of:

1) 0 and 9

2) 0 and 5

3) 0 and 25

4) 0 and 10

5) 0 and 60

6) F and A

7) Unsatisfactory and Excellent

Is this correct and complete for boundary-value analysis? The way the question is written (the “three tests for each input field part” part) makes me think that this involves equivalence partitioning in conjunction with boundary-value analysis and not boundary-value analysis alone. Does this mean I need to include a value within (and strictly excluding the boundaries of) each range and is it in fact combining equivalence partitioning with boundary-value analysis? Also, I'm very confused as to what is being asked as of “format incompatible” onward.

Any help in solving this problem completely would be GREATLY appreciated!

Thanks in advance!
