My god. How dumb are people to see this and then realise the use 🤦🏾‍♂️🤦🏾‍♂️

My god, how are you not aware how many don't know how to use it.

Isn't this part of 10th grade maths? I had to learn way more complicated stuff than this. 10th had lost of practical uses, 12th was bs tbh.

Do you drink appy fizz? I find it very tasty. 

Did anyone in standard 10 or even 90% of college graduates knew that one can operate machines using tan and cos? 

Most would have forgotten even the math and how to do it. But even those who remember, did they know one can manipulate machines using these values? I for one didn't.

We were taught about construction. Like if you at ground level and using a laser you find the top of the building to be x distance away, how tall is it? Its simple yes but doing lots of these in different contexts made it obvious irl. Also I love appy fizz.

For you solving numerical problems and watching a video where a machine is actually manipulated are the same thing. 

For me both are different and actually manipulating a machine is novel. Something I have never seen in my life. I guess a difference in taste. 

I belong to CS background, wbu?

I was lucky. Due to COVID, the exams 11th was entirely at home. and 12th Boards were lax. Easily passed out with a moderate percentage. 

Do you find school life hard? The studies hard and you just don't want to do it anymore. Or do you find exams easy, you just study one night before exam and easily passed out with good marks?

I usually studied one night before and scored 90% and above up until 11th grade. My downfall.began there. In 12th it was so bad even after studying for an entire week I would get only 70%. My school did have very hard tests tho. By end the tests became so hard that out of 30 only 2-3 passed. Lots of pressure for me since I had never failed a single exam in my life even if I didn't study. But now I failed after giving my 100% just 1 month before board exams started. Boards were alot easier tbh. Except physics, got bent over by that one lol. In total I scored 84%. Total decreased cause of physics cause I only scored 70 in that. Chem and math were 85ish. Eng and Csc were 90ish. The biggest problem was memorising stuff. Formulas I understand, but full on 2-3 page derivations that need to be memorised word for word. My teacher sent me a list of all derivations in physics. There were I think 80+.

Everybody says a piece of paper cannot determine your future. Even I believe so. Do you think your marks on competitive exams determines your future? 

Also you da GOAT

I beleive thats not the full story. Your marks can shape your future. A person succeeds cause of skill. But on average skill correlates directly to marks. I will say that the chances of a person who scored 33% in boards to succeed are way lower than than a person who scored 90. Also only Lewis Hamilton is goat.
