### Explanation of Categorization:

#### High Weightage:
These topics are frequently asked in NEET with numerical problems or conceptual questions, especially capacitors, dielectrics, and energy-related calculations.

#### Moderate Weightage:
These topics are conceptually important but appear less frequently in NEET compared to high-weightage topics.

#### Low Weightage:
These topics are foundational or introductory, helping you understand the basics but are rarely directly asked in NEET.

#### Additional/Miscellaneous:
These topics are less critical but may appear as part of advanced or tricky conceptual questions.

Respect for tanuj sir📈📈📈
Mind-blowing lecture!!
Revision Done✅

[thundergaming]

Jese jese prachand aage badh rha h confidence level high ho gya thank you sir

[SanthoshSanthosh-rn]

Any ine who is reading read it fully i was studying from mr sir since june i was thinking that i am understanding everything and did questions but there was mo use for me inwas in a imagination that if i study from mr sir i will get marks even i wasn't understanding that much it took me 6 months to realise i have attended every lecture but my concepts were a complete zero dont run behind one teacher because everyone is running... I am not telling thant mr is nlis not goob but i didn't match the vibe so choose the teachers wisely i have wasted 6 months

[Rishav.]

MR Sir 🗿
Tanuj Bansal Sir 🗿
Compare krne wale 🤡

[subhasiniiigogoi]

Literally the best physics teacher ever. He explains everything so well.. Never understood physics better with anyone else. Thank you Sir.

JO LOG END THAK THE LEGEND HO BHAI SAB🗿🗿🗿

[tejasvichorotia]

Trust me guys this lecture is amazing mujhe pehle yeh chapters bilkul nhi smjh aate the mene bohot baar y chapters alg alg teachers s padhe, mujhe lgta tha sb un teachers s pdhte h to mujhe bhi unhi s pdhna chahiye even when i am not understanding a thing, i studied from that teachers pr questions fir bhi jyada shi nhi hote the then I've found this lecture and now my each every concept is crsytal clear .
This lecture is a pure gem guys.

[JatinKataria]

One shot ❌️ Detailed Lecture ✔️
ThankYou so much Sir❤

[vinitasahu]

If anyone is confused about ki ye lec pehli bar me smjh ayega ki nahi definately smjh me aa easily aap har difficult se difficult topic samjha dete h sir ...
Thank you so much sir
Ye chapter maine mr sir se v pdhi but bahut sare confusion thi ab clear ho gaya

Note : yha teacher ko koi compare ni kr rhi bas ye bata rhi hu ki zaruri nahin hai ki jaha se 90% students pdhte h or unhe smjh ata h vhi se aap v pdhe ..ye bta rhi hu ki apki frequency jis teacher se match hoti h ap unse pdhiye

[produniya]

I have completed my 11th from MR sir but now I cant that long lectures thats why now I am taking thease one shot and tanuja sir is also best I think
