I’m a little concerned that you said having good grades would “save your life.”
There’s a story by Rabbi Joseph Telushkin in his book The Ten Commandments of Character. He asked, what do parents praise in their children? For one, it is being handsome/beautiful. Another child is praised for athletic prowess. Still another child is praised for academic prowess. That just leaves the one for whom they say, “oh, but So-and-so is really a good kid.” From this, children mistakenly learn that being a good person, doing good things, seeking the right things, is not a big deal.
It is not Telushkin’s intent that parents should be unaware of the other qualities, but rather that they should be aware that those qualities can fade. It makes life harder for the child who is led to believe that they are accepted only as long as they continue to demonstrate that momentary quality. Telushkin argues that parents should instill the higher values, the “seek-ye-first” values, the timeless values.
It is understandable to feel a little panic at the thought of getting bad grades. But in the end the pursuit of a degree shows that you have the quality of perseverance. That is more important than the ranking.
In fact, many smart people stink at taking tests. There are three styles of learning: seeing, hearing, and hand-on/doing. You might just be taking a class that teaches and tests differently than the way that you process the information.
But please consider these two more thoughts:
One: It may be mildly embarrassing to repeat a course, but it is an option. If you do repeat a course, your old final grade in the course would be replaced with the new grade.
Two: This too shall pass. It has been decades since anyone asked what my grades were.
Blessings.
