I asked a question in Chemistry StackExchange about mathematical and physical fundamentals that one should know before learning physical chemistry but it keeps getting closed as it appears to be opinion-based even after editing it two times. The main thing I ask for in my question is advice on how to prepare for physical chemistry and which literature might be helpful. How can I improve my question to make it less opinion-based?
My brief personal opinion is that questions like this are always going to be somewhat opinion-based as every person's learning curve is different. The books that are universally decent are already listed in Resources for learning Chemistry, or can be found on Amazon or an equivalent online book store offering ratings and reviews.
It's the same as to ask what Linux distro is the best for the beginners. The answer would be that there is none: just take the first one and try to learn as many new things as possible from it. When you finally feel like it has nothing extra to learn, switch to another one. Also, find and solve real-life problems: it's practice that makes perfect.
