You can check out this page here, which has a lot of information regarding World 2-4 on it: https://kancolle.wikia.com/wiki/World_2:_%E5%8D%97%E8%A5%BF%E8%AB%B8%E5%B3%B6%E6%B5%B7%E5%9F%9F#/2-4

Beyond that, what are your ship-levels looking like? How about your gear (do you have enough planes)?

If you don't have the levels on your BBVs (Yamashiro turns into a BBV at Kai), CVs or CVLs, try grinding some exps in 1-5. If you only go through the first 3 nodes there, you should be able to bring what you want...just as long as you can sink submarines.

...however there is, unfortunately, little that can be done for anybody at any level, because your greatest challenge is the compas; if you go A -> B, you can't beat the boss no matter what. If you go A -> K, there is a good chance that you will off-route (especially if you have DDs in your fleet).
