Unrelated Chemistry tips Request

[Gunroar:Cannon()]

I'm looking for tips from anyone here who's knows chemistry, cause I'm not that good at it. For example I know things in physics like just know formulas, gravity is just acceleration, kind of like life hacks for chemistry. Anyone has tips like that? I can't find any of these type of smart tips online. Links are also welcome, but personal advice is appreciated. Even more physics tips are welcome.
I'm talking about advanc-ish level physics and chemistry(just before and early university), oragnic chemistry, chmeical formulaes(like is there a way to know what mixes with what without remembering everythin?), pH, what does what, log, pi, you know...etc. I always try to study it and do questions but I always get below 50%.

Unrelated, yes. But kind of related . If you think about it Games that use physics and chemistry.

Chemistry is the study and manipulation of moleculic structures and the substances they form. Understanding what various kinds of bonds atoms make with each other is the basis of chemistry. Then there's the wide library of reactions discovered by chemists throughout history; procedures for breaking up, mixing, and joining together molecules to transform one kind of matter to another.

You'd need to ask more specific questions.

Thnx, and yes, the main part is chemical reactions. I'm fine with any thing calculation related(including radioactivity). But it's the rules some people may know about these chemicals, or facts that should be known to make understanding a chemical reaction, even one you haven't seen before, easier(i.e.to know which loses electrons and which bond is formed). And also facts anyone finds helps them that may help me,
