170. I think I got 1-16 and 20 right. I didn't even guess on 3 others. I chose 'I don't know'. Not sure the difference between doing that versus getting it wrong. I'm pretty sure I got the rest right.
So I spent some time(20-30 minutes) on the test to figure out all the answers. Here are the answers and the explanation. Spoiler 1. 8 - odd number while the others are even 2. Snake - reptile while the others are mammals 3. 9 - start by subtracting by 2 and subtract by 1 more on each number in the series. 15-6 = 9 4. 15264 - PEACH is HCAEP backwards and 15264 is 46251 backwards 5. 312 - The series is x5 +2 X5 +2 6. A - dark part of circles goes towards the center 7. True - If all Bloops are Razzies and all Razzies are Lazzies, then all Bloops are definitely Lazzies. 8. 128 - The series is X2 or 2^n 9. 24 - 16 = 4x, x=4, 16-4=12 years apart, 12x4=24 10. 4 - The next number in the series equals the sum of the two preceding numbers. 11. B - hard to explain but obvious 12. F - From the left to right, the third box is filled in the areas that the two preceding boxes weren't 13. 225 - n^2 is the series 14. C lied, B cheated - A: C won't cheat unless B cheated. True B: Maybe one of A or C cheated. True since "maybe" isn't lie C: B didn't cheat, it's me cheated. - Lie D: B cheated. -True 15. -5, top number minus the middle number equals the sum of the digits of the bottom number. 4 - (-5)= 2+7 16. 8 - Since cards 1 and 7 are the last cards placed down. 8 had to be the start with cards being place down in a clockwise fashion 17. 95 - series is preceding number + (5 + 4n) 18. 17 - sum of all the digits of the numbers in the above row give you the first number in the row. 13 and 49 gives you 1+3+4+9=17 19. H - All numbers on the top row are symmetrical on the vertical axis and all the number on the bottow row are symmetrical on the horizontal axis. Only the letter H is symmetrical on both axis's. 20. A. - the symbols on the 3 column are inverse at 45 degree axis with vertical being 0 degrees.
