How to make the scenes change automatically?

I want to make it like when you finished one level, you will be taken to the next level (which is on the next scene) automatically.
Should I use any scene behavior? If so, can you tell me which ones should I use? Or do I use any settings?
Any helps would be so appreciated. 
 I need to finish this game ASAP as it is for a school project.

Use the switch to scene block and set the transition time to 0.01 seconds once the conditions to ending a level in your game are met.

See the blocks under SCENES > GAMEFLOW > TRANSITIONS

Those blocks will let you change scene. The first thing you need to do is figure out how to check that the current level is completed. What are your criteria for completing a level?

You can use one of these blocks (attached)
