A lot of things we learn go down the drain.Whatever we learn throughout in schools is not necessarily applied in real life.
Example, Trigonometry and Algebra I can't find a use for them in pratical or even theoretical life. Even the number of planets we learnt have changed. There were 9 planets including Pluto but now there are only 8, Pluto is no more a planet.
What's is the use of such studies, its like teaching the fish to climb a tree.
I am not here to discuss the education system, it must have been discussed a thousand times on this platform but want the member to share their experiences of things they learnt as student but never got a chance to apply it in real life or even understand why did we learn what we did.
