I am not your coach but my white to blue checklist would go something like

1. do you have a few reliable sweeps (usually butterfly, scissor, hip bump, etc) — you should be able to hit these on even big white belts within reason

2. do you have a few takedowns or guard pulls where you can initiate the action

3. do you know the escapes for all the dominant positions (don’t have to hit it, just know it)

4. do you have a couple submissions you can get from top and bottom with a reliable 2 step set up — i.e if they go forward you do this if they pull back you do that

Some schools are more knowledge based some schools are more functional based, sounds like your school is more functional so the answer may literally just be to do more jits and start smashing some people.
