Ah, R ko units ta chitta dukhayeko kura ho bhai! ☹️ If you mix up 0.0821 with 8.314, your whole answer becomes nonsense, and the teacher won't give a single mark. I learned the hard way when I used the wrong 'R' for a pressure question in my last exam. Even though my method was perfect, that one slip made my paper look like a grocery list in wrong units. Now I double-check the units like I check for leaky pipes.
