On this page of the Spider-Man Miles Morales guide, we have described the Benchmarks, bonus tasks you can complete during the game.
You can find the tests in the 8th tab after pressing the touchpad. These tasks are divided into traversal and combat tests. Completing each achievement in the test will reward you with Experience Points.
Achievements are related to performing a certain ability or defeating an enemy in a certain way a certain number of times. Each Benchmark is divided into 3 achievements, and for completing the entire test you will receive stickers that can be used in photo mode.
