Question:

A diver can hold his breath for two minutes under water. After practicing for a week, he can hold his breath for 5% longer. How long will he be able to hold his breath after the first week of practice?

A 2.1 minutes
explanation

First, calculate 5% of 2: 2 × 0.05 = 0.1
Then, add this increase to the amount of time the diver could originally hold his breath:
2 + 0.1 = 2.1 minutes

Only tired a few categories. I was most looking forward to assembling objects. It shows microscopic diagrams that you can't zoom in on, and asks in regular question format which will make an object of assembled. I can't see the pic, and the answers are straight up A.B.C.D. with no hints of anything else. ??? Also, a LOT of ads for games and stuff. Every screen is a new ad for color match or cartoon me.
