What do you think of this time saving secret by the bible?

It says if you give your working time to God, God will reduce the time it takes for you to finish your daily activities.

I remember in university, I had a normal selfish and lonely 4 days and then spent a full day on an assignment and got an A- on it.

Later I spent time at a bible study and did the exact same questions on a new artifact of analysis, graded the same way as the previous project, and I spent 30 minutes on the exact same assignment and got an A- on it.

My friend said he studied like crazy and got C’s but after he began to volunteer at church, he reduced his study time in half and his grades were 25% higher.
