which ones am i getting wrong?

[Honest]

i have no idea how to solve 23. pretty much guessed the other 3 too

explain the pattern/logic

PART 1:
each row/column has, in total:
3 white triangles
1 black square
1 white square
1 black triangle
3 black circles

so final square must have:
0 white triangle
0 black square
1 white square
1 black triangle
1 black circle

so it must be either B or F

PART 2:
black circles are moving leftwards along rows
and black circles are moving rightwards down columns


so it must be F

when i was taking the test, i didnt notice B, and so was lucky enough to click F as soon as i had solved part 1. was confused as to why you didnt get it as i thought it was one of the easier questions, now i realise it was deeper than id thought
