I have found that I understood about the max. rotation was wrong. I thought it was the clockwise rotation of the images from the options but it is actually the clockwise rotation of the original image. Though, I really enjoyed the test.

Hmm....I still see only 10 squares for C, but 11 squares for D in #13. What am I missing?

For that problem, C has 12 (1 1x1, 4 2x2, 5 3x3, 2 4x4)

Check C again. It has
One 1x1 squares
Four 2x2 squares
Five 3x3 squares
Two 4x4 squares

Hah...well, based on the 25% success rate, I guess I'm not the only one who had a blind spot...

This contest may be great for identifying truly skilled puzzle solvers but I really did not have much fun (and if puzzles are not fun, why do them?). Too many of the questions seemed to be "how quickly can you count and remember totals under pressure". And I cannot do weights or minesweeper puzzles entirely in my head. So I ended up trying to use intuition or taking a guess. But maybe it's just me...a lot of others seem to really enjoy it.
I shall look forward to the next regular contest next week. Thanks

Great puzzles, but in the latter part, paper was necessary for me. (Especially Mines)

As far as Screen Tests go that was pretty interesting.

So, a quick walkthrough for the more tricky puzzles (those that aren't just "just count"):

Shades: Count least white squares.
Perimeter: Slide lines outside to form a rectangle.
Triangles: Count 1-triangles, then 2-triangles (made of two small triangles), and so on.
Circles: Fingers are your friend. Keep track with your fingers on the screen.
Sums: Discard the 99s. If you're quick, you can do all 24 possible sums; if not, you can prune this by starting by using the 7, and if not then the 6s, and so on.
Rotation: Find the one that rotates counterclockwise the smallest. Take two or three consecutive terms and find them in the options to determine the angle.
Weights: Top bar means A+B+C=9, D+E+F=12. Top-right bar means D+E=6, F=6. That's enough to determine the heaviest weight.
Total: Work from bottom to top. Just before the last row, you definitely want to move to the bigger number. Replace the second bottom-most row with this result (2, 1, 3, 1, 1) and discard the bottom-most row. Continue with the third bottom-most (8, 8, 11, 10), and so on. Best done on paper.
Squares: Count 1x1, then 2x2, and so on.
Mines: Corners sum to 7, so there are at most 12 mines (corners + 5 making the plus shape in the middle). Try that. Edges sum to 11, with the center square it's 12, so the diagonals (except the middle) are otherwise empty. This leaves 7 mines in 8 squares, easily checked.
Solutions: A has one solution, the rest zero. B's contradiction: R1-2C5 means R3-4C6 are 23, which means R5-6C4 are 23, but R5C4 is blocked. C's contradiction: R1C4 and R3C4 must both be 1 (by respective box and C4). D's contradiction: R3C2 must be both 1 and 4 (1 by C1 and C3, 4 by R4).
Shapes: L is contained in M many times, so L must be more than M. Whenever I is on the grid, you can extend it to a H, which includes L many times as well.
Distance: Try to link a letter to another letter, so that one of them uses the other in the shortest path; this rules out the latter.
Instructionless: Largest number when all digits are read from that direction.

Of course, the best puzzles are Weights, Mines, and Shapes. I'd like to choose Solutions as well but I don't think those contradictions can be made really quickly; I ended up just doing them on paper, deriving numbers as many as I can until I find a contradiction.

Or, just solve it as a Maze.
