i want to know the current pattern examof bsc biosciences of jmi( as in its syllabus it is written only 50%of questions will come from bio n 50% will come from pcm what about eng n curraffirs) is sufficient if i read only ncert of 11th n 12thn do some objective book for practice ..can i crack it?

Sreeja Siva 3rd Oct, 2020

Hi,

Usually the entrance exams for UG courses are mainly based on plus two syllabus. So you should stick to the basics. Also please check the previous year question papers if available. You can crack it if you prepare well. Know your subject well and go for it. Workout the sample and previous year question papers. All the best.

For what chapters reading ncert only enough.. And for what chapters we have to refer more... And am asking for bio subject of neet.

Shivanshi Singh 24th Aug, 2020

Hello,

NCERT can help you to the great extent if you are preparing for NEET , If you are going through each and every topics thoroughly and understanding each concepts than you don't need extra materials to refer . I suggest for  practice and referance  refer some previous year papers  it will help you to understand type of questions generally asked.

All the best

Thankyou

How many questions will directly come from ncert( biology of neet exam). And how many questions will be out of ncert?

priyaankasarkar Student Expert 24th Aug, 2020

NTA conducts NEET in offline mode which means the question papers are not released and so it is difficult to check which questions have been asked from which book. But in general 98% of the questions in NEET come from NCERT books alone. But based on previous years of paper analysis weightage has been calculated for each topic. Human Physiology and Genetics have maximum weightage in NEET. Diversity of Living Organisms has 14% weightage. Structural Organisationi n Plants and Animals takes 5%. Plant Physiology has 6% and Cell Structure and Function has 9%. Human Physiology has 20% weightage. Reproduction chapter has 9% and Genetics and Evolution has 18% weightage. Biology and Human Welfare has 9% weightage. Biology and its application has 4% weightage and Ecology and Environment has 6% weightage.

list all the exceptions in D and f block chapter in class 12 ncert for neet.

Mayank Chowdhary 23rd Aug, 2020

D block elements are called as transition elements. F block elements are called as inner transition metals. F block elements were actually a part of group 3 only but due to some similarities in their properties they got a different space in f block table.

Kindly refer to the link below for knowing more about these elements.

Im not good in physics but wanted to do btech(electrical engineering). so studying ncert physics (class 11&12) sufficient for btech

Manasi Kadam 1st Oct, 2020
Hello there,

NCERT books are good for making your base strong in physics but the language of physics ncert book is quite confusing and finding important points consumes a lot of time since they have big paragraphs written for stuffs that don't require this much information.

Although, the exercise questions of ncert physics miscellaneous exercises are really good they will definitely make your base ready for btech in electrical engineering.

You may also refer books like
Concepts of physics hc verma
Physics Modern abc ( they are good for boards and explain ncert stuffs in a way simpler manner)
Make use of internet...there are notes of each chapter available in pdfs u can check them out.

Hope this helps!
All the best!

what are the chapters i have to study to score 200+ in neet biology and is NCERT is enough to score 200+ in biology?

Aishwary Jaiswal 20th Aug, 2020

hello,

well, to be honest ,scoring 200+ marks in neet exam won't do much help to you, yo will have to face a lot of problems to get a good college .

studying from NCERT will surely clear up all your doubts, but it is strongly recommended for you to refer some of the other books as well and make sure that you try to achieve 550 + marks in the exam.

nothing is impossible, don;t worry, you can do it.


refer the link for the books-

list all the exceptions in the periodic table chapter of class 11 ncert.

Yash Chouhan 17th Aug, 2020

Hello Aspirant,


Variation in ionisation enthalpies: Ionisation enthalpy increases with increases in atomic number along the period. Some elements show irregularities in this trend due to type of electron to be removed and the extra stability of the exactly half-filled and completely filled electronic configurations.

Variation along the period: In the second period Li to Be, the ionisation enthalpy increases due to increased nuclear charge and smaller atomic radius of Be as compared that of Li. For Be to B, although the nuclear charge of B is more than that of be, yet the ionisation enthalpy of B is lower than that of Be. For B to C to N, the first ionisation enthalpy of these elements keeps on increasing due to progressively increasing nuclear charge and decreasing atomic radius. For N to O, the first ionisation enthalpy of oxygen is lower than that of N although the nuclear charge of O is higher than that of nitrogen. For O to F to Ne, the first ionisation enthalpy increases from O to F to Ne because of the increasing nuclear charge.

Similar variations in the first ionisation enthalpies of the elements of the third period have been observed.

Variation of electron gain enthalpy in a group: In general, the electron gain enthalpies become less negative as we move down a group. But the electron gain enthalpies of some of the elements of second period that is O, and F are however, less negative than the corresponding elements that is s and Cl of the third period.

Thus the electron gain enthalpy of F is unexpectedly less negative than that of Cl.

Also the electron gain enthalpy of noble gases is positive as atoms of these elements have completely filled subshells.

Variation in atomic radii: The atomic radius abruptly increases as we move from halogen (F) to the inert gas (Ne). This is due to the reason that in case of inert gases all the orbitals are completely filled and hence the electronic repulsions are maximum.

Variation of valence in a period: As we move across a period from left to right, the number of valence electrons increases from left to right, the number of valence electrons increases from 1 to 8. But the valence of elements with respect to H or O first increases from 1 to 4 and then decreases to zero.

Electronegativity

This is the easiest of the exceptions. We have said that electronegativity increases to the right. This is true except that the trend does NOT include the noble gases. That means that fluorine has the highest electronegativity, not Ne or He. This is because the definition of electronegativity contains the phrases "in a covalent bond." Since the noble gases don't bond, they don't have electronegativities.

It should be noted that a few of the noble gases have been forced to bond (at high temperture and high pressure with fluorine). You may find tables that, therefore, list values for the electronegativity of Xe and Kr, but these are not terribly important values to know.

Hope this helps,

All the best and thank you!

in the neet ques paper 2020, one ques was there that " some dividing cells exit cell cycle and enter vegetative stage called Go phase . this process occur at the end of ? acc to allen akash n ncert dia.ans is M phase but today nta ans key gave G1 as ans. so whatever nta abs key says is final ?

Ethan Hunt I 7th Oct, 2020

Forget 3 words for a minuit:AAKASH,ALLEN and NCERT.

There are 3 checkpoints in the cell cycle. One between G1 and S phase,the other between G2 and M phase and the other between Metaphase and Anaphase.The G1/S checkpoint plays THE MAJOR role in G0 phase transition according to Wikipedia,Brittanica,Khan Academy (to name a few).So no matter what answer is given by NTA,I would consider G1 phase to be the logically correct answer.

PEACE

is ncert enough to get 100 Marks in upsee chemistry and physics?

rehan18alam Student Expert 17th Aug, 2020

Dear Aspirant,

Although the difficulty level of UPSEE is on the easy side, depending solely on the NCERT is not a good option, I would suggest with NCERT you must use some previous year question paper books as they will give you a practical idea about what sort of questions will be asked and therefore you can prepare accordingly.

Hope this helps Thank you.
