Whether you’re battling JEE, wrestling with Class 11 & 12 topics, or diving into some tasty code, you’ve found your spot. Here, everything’s laid out like a cheat sheet 📘 to life: physics, chemistry, math formulas, programming tricks, and the oh-so-sneaky shortcuts that’ll make you wonder why everyone else finds it so hard.
Open ( yes, you can edit these notes yourself! ), free, and overflowing with stuff you’ll actually use – feel free to binge, bookmark, and bless your exams with the power moves stored right here. Study smart, learn faster, and leave ‘em wondering what your secret is! 💡🔥
Ye be sailin’ in the right waters if yer after secrets t’ conquer the high seas o’ exams! From formulas and magic scrolls fer JEE battles to sneaky tricks fer ye everyday curriculum in Class 11 an’ 12, this be the hoard ye seek. Ye’ll find the finest charts fer physics, chemistry, math, an’ even some coded enchantments fer ye clever pirates. 🧠
Plunder freely an’ carve yer name on it, me hearty – no coin needed! Binge it all, stow it fer later, an’ give yer mind the compass it needs t’ steer straight fer success. Now, go forth an’ show them landlubbers who rules the waves! ⚓️💀
Mathematics is the abstract science of numbers, patterns, structures, space, and change, using logic and symbolic reasoning to understand relationships.
A system of rectangular coordinate axes divides a plane into four quadrants. An angle $\theta$ lies in one and
only one of these quadrants. The change and sign of the trigonometric ratios in the various quadrants are shown in Fig-1 below.
Sum and Difference

$\begin{aligned}
\sin(A\pm B) & = \sin A\cos B\pm \cos A\sin B \\[3mu]
\cos(A\pm B) & = \cos A\cos B\mp \sin A\sin B
\end{aligned}$
Physics is the study of matter, energy, motion, and fundamental forces, aiming to explain the behavior and structure of the universe through observation and theory.
Induced EMF $\mathcal{E}_2$ in $\text{coil}_2$ due to change in current $i_1$ in $\text{coil}_1$: $\mathcal{E}_2 = -M \dfrac{di_1}{dt}$
Chemistry
Chemistry is the scientific study of the composition, structure, properties, and transformations of matter, and the energy changes that accompany these processes.
Common names are often used colloquially and in everyday life but lack a systematic approach like IUPAC nomenclature. These seemingly arbitrary names can hinder your understanding and ability to solve problems, as exam questions may use common names that you might not be familiar with. To overcome this, it’s essential to familiarize yourself with common names and their corresponding structures.
Resources
[!Orange] Note
This list may and will be updated in future as I add more resources.
PDFs I collected that included common names and their corresponding structures.
(Sorry, but I didn’t consider noting the sources of some of these PDFs at that time.)
