If you are interested to learn at IIT then , only one option is apply all IIT's for MS ( core subject as well as interdisciplinary Branches) , prepare for virtual interview, (not for Ph.D)....

Here are the notes I have written during my preparation for GATE CS/IT. Future aspirants may find it helpful. These are elaborated notes, that one may go through to recapitulate stuff fast. I took help from standard books and online courses to put together these notes. As of now, only some chapters of Discrete Mathematics are uploaded. I will upload notes for all the subjects within a month.

Sample note(on Combinatorics):  

Can anyone upload a DRDO previous year papers/ link.

I don’t remember completely but someone had pasted the link on a blog here a year ago.

Thanks in advance. Gateoverflow is one the most wonderful site I had ever used in my entire Journey to AIR 89.

$$\color{Blue}{\textbf{Calculus}}$$

$$\color{Magenta}{\textbf{1.Trigonometry}}$$

$\textbf{Pythagorean Identities:}$

$\sin^{2}\theta + \cos^{2}\theta = 1$ $1+\tan^{2}\theta = \sec^{2}\theta$ $1+\cot^{2}\theta = \csc^{2}\theta$

$\textbf{Reciprocal Identities:}$

$\sin\theta = \dfrac{1}{\csc\theta}$ $\cos\theta = \dfrac{1}{\sec\theta}$ $\tan\theta = \dfrac{1}{\cot\theta}$ $\csc\theta = \dfrac{1}{\sin\theta}$ $\sec\theta = \dfrac{1}{\cos\theta}$ $\cot\theta = \dfrac{1}{\tan\theta}$

$\textbf{1.Properties of determinants:-}$

The determinant is only valid for the square matrix.

$\mid A^{T}\mid = \mid A \mid $ $\mid AB \mid = \mid A \mid \mid B \mid $ $\mid A^{n} \mid = \big(\mid A \mid\big)^{n}$ $\mid kA\mid = k^{n} \mid A \mid$, here $A$ is the $n\times n$ matrix. If two rows (or two columns) of a determinant are interchanged, the sign of the value of the determinant changes. If in determinant any row or column is completely zero, the value of the determinant is zero. If two rows (or two columns) of a determinant are identical, the value of the determinant is...
