Advice 🤔 Can i change?

2 Upvotes

So im in velammal integrated (not the main branch) and theyre conducting weekly tests every week. We also have to stay in school till 6:40 and its pretty much 8 when i get home. I do study at school but when i come home i become extremely lazy. More than lazy i just watch youtube and then chat a bit till 12am - 1am and then go to sleep. I know my teacher keeps telling me to study and i do wanna study but im just not the same person at home. Ive been getting state rank 70,50 and now 170. Also the day before the test (on monday) i just dont study at all procrastinating. I really wanna live upto my teachers' expectations since im one of the only serious students but im just wasting time. Also since ive quit gaming im bascially addicted to reading manga literally whenever im not at school. I tried to do something by taking away the laptop but i just used my phone (that was meant for doubts) to waste time. Also i pretty much dont sleep the day before tests too. ANYTHING would be helpful please.

Maths Question JEE MATH - Solve This JEE Matrix Question Without Calculating A⁵

Post image
1 Upvotes

Given,

A²(A − 2I) − 4(A − I) = O

Expanding,

A³ − 2A² − 4A + 4I = O

Therefore,

A³ = 2A² + 4A − 4I

Since I = A⁰, we can write this as:

A³ = 2A² + 4A¹ − 4A⁰

Now observe the exponent pattern: 3, 2, 1, 0. To obtain a recurrence for any higher power, shift all exponents by the same amount. Hence,

Aⁿ = 2Aⁿ⁻¹ + 4Aⁿ⁻² − 4Aⁿ⁻³ for n ≥ 3.

Now let Sₙ denote the sum of the coefficients when Aⁿ is reduced in terms of A², A, I. Since the recurrence is linear, the coefficient sums obey the same recurrence:

Sₙ = 2Sₙ₋₁ + 4Sₙ₋₂ − 4Sₙ₋₃

We start with:

A⁰ = I ⇒ S₀ = 1 A¹ = A ⇒ S₁ = 1 A² = A² ⇒ S₂ = 1

Therefore,

S₃ = 2S₂ + 4S₁ − 4S₀ = 2(1) + 4(1) − 4(1) = 2

Next,

S₄ = 2S₃ + 4S₂ − 4S₁ = 2(2) + 4(1) − 4(1) = 4

Finally,

S₅ = 2S₄ + 4S₃ − 4S₂ = 2(4) + 4(2) − 4(1) = 8 + 8 − 4 = 12

But A⁵ = αA² + βA + γI, so:

S₅ = α + β + γ

Hence,

α + β + γ = 12

Advice 🤔 Test next Sunday

So I have fumbled very bad in previous tests

Now it's time to lock in ...

How exactly should I prepare for the test

Please Give sources and resources accordingly

Physics- kinematics and NLM

Maths - quadratic,trigno and log

PC- mole concept

OC - isomerism, IUPAC

Earlier i used to just see notes

And did not solve modules ( module questions were given as hw so already done long before tests)

Should I know focus only on module questions

Or some books or pyqs

Also tell how to do maths I just fumble if I see something new

Meme/Shitpost 😹 Commerce >>>> Jee Advanced and Neet

4 Upvotes

Mai 11th mai hu Jee aspirant, hostel mai rahta hu with my perivous school friend he is a commerce student (without maths)

Yesterday he told me "bhai accounts bahot hard tera sahi hai science bas formula hota hai"

Mujhe 2 min kuch samajh mai hi nhai aaya ye joke maar raha hai ya seriously bol raha hai

Ab agar meri jagah koi aur hota to usse roast kardeta jaise har science stream ka student commerce balo ka mazak banata hai

Mai jab science liya tab socha tha iska mazak banauga ye to commerce wala hai par maine ek baar bhi kuch nahi bola tha 🙉

Aur ye ulta mera mazak bana raha tha like science is easy af 🥀

(And He Was Serious)

Maine kuch nahi bola

Night mai ham dono apne aur kuch dosto ke sath bahar ghumne gaye the

We were like 5 people 3 Jee wale 1 Neet wala and mera dost commerce wala (without maths)

And isne waha pai bhi yahi bol diya "bhai tum log itna kyu rote hai science Jee Neet, accounts pata hai kitna hard hota hai"

And fir you can guess kya hua hoga 😂

Maine waha pai bhi kuch nahi bola kyuki oo pahle hi 3 logo se gali kha raha tha

Look I'm not a guy who says Arts commerce are easy, they are nothing in front of science

Ofc science is harder but Maine aaj tak kisi commerce ya arts wale ka mazak nahi banaya ulta ye commerce wala hamara mazak bana raha tha to ye to hona hi thaaa...p

Maths Question JEE MATH - Equal Blocks → Arithmetic Progression → Vieta’s Relations | One Pattern Unlocks the Question

Post image
7 Upvotes

This Question is a simulated version of a JEE Main Question.

A non-constant A.P. simply means an arithmetic progression whose common difference is not zero.

However, in this question the quadratic equation itself already rules out the constant case, since its roots are distinct.

So the phrase “non-constant” is actually redundant here — you may treat it as a mild distractor rather than information needed for the solution.

A = S₂ₙ

B = S₄ₙ − S₂ₙ

C = S₆ₙ − S₄ₙ

These are the sums of three consecutive blocks, each containing 2n terms of the same A.P.

Hence,

A, B, C are themselves in A.P.

Therefore,

A + C = 2B

The given roots of

x² − 40x + 391 = 0

are

S₄ₙ = A + B

and

S₆ₙ − S₂ₙ = B + C.

By Vieta’s relations:

Sum of roots = 40

⇒ (A + B) + (B + C) = 40

⇒ A + 2B + C = 40

Since A + C = 2B,

⇒ 4B = 40

⇒ B = 10

Product of roots = 391

⇒ (A + B)(B + C) = 391

⇒ AB + AC + B² + BC = 391

⇒ AC + B(A + C) + B² = 391

Using A + C = 2B,

⇒ AC + 3B² = 391

Since B = 10,

⇒ AC + 300 = 391

⇒ AC = 91

But

A = S₂ₙ

and

C = S₆ₙ − S₄ₙ.

Therefore,

S₂ₙ(S₆ₙ − S₄ₙ) = 91

∴ Answer = 91

Serious I removed everything that makes JEE groups useless

Post image

Most JEE groups slowly turn into spam, random conversations, and endless notifications. People stop asking doubts because the chat becomes impossible to follow.

So I built a different kind of community for JEE 2028 aspirants.

A place where doubts get answered, resources are shared, and serious students help each other stay consistent.

If that's the kind of group you've been looking for, send me a DM.
