Do you have problems with specific ladder jumps or are you just struggling with ladder jumps in general?
If you have problems with ladder jumps in general, then I can just repeat what Ayzzaphe said before. If the ladder is a little bit further away it mostly is necessary to sneak when you land on the ladder. Always try to get as much momentum as possible, then it'll surely be easier to reach the ladder.
However, if you have problems with specific ladder jumps, feel free to post some pictures of those jumps here or dm me on Discord (@Mika#0065) and I'll try my best to help you!
Have a nice day ^^
