Important Physics Formula For NEET 2026 - Series LCR Circuit
Let i be the amount of current in the circuit at any time, and VL, VC, and VR the potential drops across L, C, and R, respectively.
$v_R = iR \Rightarrow$ Voltage is in phase with $i$,
$v_L = i \omega L \Rightarrow$ Voltage leads $i$ by $90^{\circ}$,
$v_C = i \omega C \Rightarrow$ Voltage lags $i$ by $90^{\circ}$.
By all these, we can draw a phasor diagram as shown below –
So, from the above phasor diagram, V will represent the resultant of vectors VR and (VL−VC).
So the equation becomes –
$V = \sqrt{V_R^2 + (V_L - V_C)^2} = \sqrt{(iR)^2 + (X_L - X_C)^2} = \sqrt{(iR)^2 + \left( \omega L - \frac{1}{\omega C} \right)^2} = iZ,$
where $Z = \sqrt{R^2 + \left( \omega L - \frac{1}{\omega C} \right)^2}$ is called the impedance of the circuit.
Also, $\tan \phi = \frac{V_L - V_C}{V_R} = \frac{X_L - X_C}{R} = \frac{\omega L - \frac{1}{\omega C}}{R}.$

Important Formulas For NEET Physics - Equations Of Motion of SHM
As we know, $a = -\omega^2 x$
General equation of SHM
1. For Displacement:
$x = A \sin(\omega t + \phi)$ ; where $\phi$ is the initial phase and $(\omega t + \phi)$ is called the phase.
Various displacement equations:
(1) $x = A \sin \omega t \Rightarrow$ when the particle starts from mean position towards right.
(2) $x = -A \sin \omega t \Rightarrow$ when the particle starts from mean position towards left.
(3) $x = A \cos \omega t \Rightarrow$ when the particle starts from extreme position towards left.
(4) $x = -A \cos \omega t \Rightarrow$ when the particle starts from left extreme position towards right.
2. For Velocity ($v$):
$x = A \sin(\omega t + \phi) \Rightarrow v = \frac{dx}{dt} = A \omega \cos(\omega t + \phi) = A \omega \sin\left(\omega t + \phi + \frac{\pi}{2}\right)$
3. For Acceleration ($a$):
$x = A \sin(\omega t + \phi) \Rightarrow v = \frac{dx}{dt} = A \omega \cos(\omega t + \phi) = A \omega \sin\left(\omega t + \phi + \frac{\pi}{2}\right)$
$\Rightarrow a = \frac{dv}{dt} = -A \omega^2 \sin(\omega t + \phi) = A \omega^2 \sin\left(\omega t + \phi + \pi\right) = -\omega^2 x$
So, the phase difference between $x$ and $v$ is $\frac{\pi}{2}$.
Similarly, the phase difference between $v$ and $a$ is $\frac{\pi}{2}$.
And, the phase difference between $a$ and $x$ is $\pi$.
Differential equation of SHM:
$\frac{dv}{dt} = -\omega^2 x \Rightarrow \frac{d}{dt}\left(\frac{dx}{dt}\right) = -\omega^2 x \Rightarrow \frac{d^2x}{dt^2} + \omega^2 x = 0$
If the motion of any particle satisfies this equation, then that particle performs Simple Harmonic Motion (SHM).

Important Chemistry NEET Formula 2026: Shapes of Molecules
The ideal shapes of molecules, which are predicted based on electron pairs and lone pairs of electrons, are mentioned in the table below:
Important formulas from Solubility and Solubility Products for NEET 2026
General Representation:
$A_xB_y \rightleftharpoons xA^{+} + yB^{-}$
$K_{sp} = [A^{+}]^x [B^{-}]^y$
Relation between Solubility ($s$) and Solubility Product ($K_{sp}$):
$A_xB_y \rightleftharpoons xA^{+} + yB^{-}$
If solubility is $s$, then $[A^{+}] = x s$ and $[B^{-}] = y s$
Thus,
$K_{sp} = (x s)^x (y s)^y = x^x y^y s^{x + y}$
The Gas Laws — Boyle’s Law (Pressure–Volume Relationship):
$P \propto \frac{1}{V} \Rightarrow PV = k \; (\text{at constant } T)$

Thank You
First, understand the NEET syllabus clearly for Physics, Chemistry, and Biology. Focus only on the NCERT syllabus, as most NEET questions are directly or indirectly based on NCERT, especially in Biology and Chemistry. Avoid unnecessary reference books at this stage.
Divide your 4 months into phases. In the first 2 months, focus on completing the entire syllabus. Study Biology daily, as it carries the highest weightage. Read NCERT Biology line by line, make short notes, and revise regularly. For Chemistry, give priority to NCERT for Inorganic and Organic Chemistry. Practice basic numericals and reactions consistently. In Physics, focus on understanding concepts and practicing standard questions rather than memorizing formulas.
In the third month, start intensive revision along with topic-wise and full-length mock tests. Analyze each test carefully to identify weak areas and work on them. Improve time management and accuracy during this phase.
In the last month, focus mainly on revision and mock tests. Revise NCERT multiple times, especially Biology diagrams, tables, and examples. Avoid learning new topics at the last moment. Maintain a proper sleep schedule and take short breaks to avoid burnout.
Stay consistent, avoid distractions, and believe in your preparation. Even a few focused hours daily with proper planning can make a big difference. All the best!
Scoring 600+ marks in NEET within 4 months is definitely challenging, especially if you are starting almost from scratch, but it is not impossible. It largely depends on your discipline, daily study hours, clarity of basics, and how smartly you plan your preparation.
First, you need to be very realistic and focused. In 4 months, your main goal should be to strengthen NCERT-based concepts rather than trying to study everything in extreme detail. NEET questions are largely NCERT-oriented, especially in Biology and Chemistry. If you can master NCERT thoroughly, your chances improve significantly.
Biology should be your top priority because it carries the maximum weightage and is comparatively scoring. Read NCERT line by line for both Class 11 and 12. Revise multiple times and practice MCQs daily. Even if Physics feels tough initially, focus on high-weightage and formula-based chapters like Modern Physics, Current Electricity, Semiconductors, Ray Optics, and Laws of Motion. Chemistry can be divided smartly: give more time to Organic and Inorganic NCERT, and practice numericals regularly for Physical Chemistry.
You should ideally study 10–12 focused hours daily with a fixed timetable. Daily revision and weekly full-length mock tests are extremely important. Initially, your mock scores may be low, but what matters is consistent improvement and learning from mistakes. Analyze each test carefully to understand weak areas.
Since you are already enrolled in another college, time management becomes even more important. Try to minimize distractions and use early mornings or late evenings effectively. Avoid too many reference books; stick to NCERT and one reliable question bank.
That said, aiming for 600+ in 4 months is ambitious and depends on your learning speed and consistency. Even if you fall slightly short, a strong score improvement can still open opportunities in government or private colleges depending on category and cutoff trends.
Stay disciplined, trust the process, and do not compare your journey with others. Many students have made significant jumps in short durations with focused effort. All the best.
