JEE-ADVANCE 2018 ANALYSIS

 

This analysis will be helpful to those who appeared for the paper, as well as those who will be appearing for it in coming years. We are going to discuss the paper pattern, new changes introduced by IIT this year, difficulty level and topic distribution.

Paper pattern

Paper – 1

	MCQ (multiple options correct)	MCQ (single option correct, comprehension type)	Decimal answer	Total
Number of questions	18	12	24	54
Marks per question	4	3	3	180
Partial marking	+3, +2, +1	NA	NA	NA
Negative marking	-2	-1	0	NA

This year, decimal value answer type questions were a new feature – in these questions, students were asked to enter the correct numerical value in decimal notation, upto the second decimal place.

IIT also notified that for correction, answer will be rounded off to the nearest decimal place.

Also, it will be considered if the answer entered by the student falls within a range of values. For example, if an answer is the number 3.55, then 3.54 and 3.56 will be correct.

If an answer is the integer 11, all answers entered as 11, 11.0 or 11.00 will be correct.

Apart from this, matrix match was different this year compared to what is usually is.

Students were given 4 options, with possible matches, and they were to choose one out of the 4.

Single option correct type questions were only asked in comprehension type questions.

Paper – 2

	MCQ (multiple options correct)	MCQ (single option correct, matrix-match type)	Decimal answer	Total
Number of questions	18	12	24	54
Marks per question	4	3	3	180
Partial marking	+3, +2, +1	NA	NA	NA
Negative marking	-2	-1	NA	NA

Last year, matrix match type questions consisted of three columns.

This year, matrix-match consisted of 2 columns and had 4 options

Note that Multiple correct questions, and decimal type questions were common to paper 1 and paper 2, and were present in the same number in both. The difference was that paper 1 had Paragraph type comprehension questions, while paper 2 had match the column questions.

Grade-wise distribution

Let us now see the distribution of questions according to class – 11th or 12th.

Physics –

	Number of questions		Marks		Percentage (mark-wise)
Grade	11th	12th	11th	12th	11th	12th
Paper 1	13	5	43	17	71.6%	28.4%
Paper 2	10	8	33	27	55%	45%
Total	23	13	76	44	63.3%	36.7%

Class 11th was given more importance

Chemistry –

	Number of questions		Marks		Percentage (mark-wise)
Grade	11th	12th	11th	12th	11th	12th
Paper 1	3	15	10	50	16.6%	83.4%
Paper 2	4	14	12	48	20%	80%
Total	7	29	22	98	18.4%	81.6%

Class 12th was been given more importance.

Maths –

	Number of questions		Marks		Percentage (mark-wise)
Grade	11th	12th	11th	12th	11th	12th
Paper 1	8	10	25	35	41.6%	58.4%
Paper 2	6	12	21	39	35%	65%
Total	14	22	46	74	38.3%	61.7%

Class 12th was given more importance.

So in short, you can say that even though class 12th is given more importance in jee advanced, we wouldn’t suggest you to leave class 11th syllabus as most of the concepts of class 12th are based on concepts of class 11th, especially in chemistry.

Give importance to both 11th and 12th!

Topic wise distribution –

Physics –

Section	Number of questions
General physics	5
Mechanics	12
Oscillations and waves	4
Thermal properties of matter and thermodynamics	3
Electromagnetics	8
Modern physics	3
Light and its properties	1

Mechanics is given maximum importance – even in previous years. Make sure you devote enough time to mechanics, electromagnetics.

Chemistry –

Topic	Number of questions
physical	14
inorganic	10
organic	12

Mostly students tend to ignore inorganic chemistry. While its questions are least this year, we still suggest you to study these as its questions are scoring – if you are good at recalling information, you will be able to score full in these.

Do not leave inorganic chemistry

Maths –

Topic	Number of questions
calculus	12
trigonometry	4
algebra	9
matrices & determinants	2
coordinate geometry	5
vectors and 3d	4

Importance – calculus > algebra > coordinate.

This has remained same in previous years. So make sure you devote enough time to these three topics.

Marks vs Rank analysis

Our experts have analysed papers from previous years and based on that and this year’s difficulty level, have prepared a rank vs marks list. According to our experts, if you score around 270 marks, you should lie in top 100 students. If you score around 255, you should be in top 500.

Year	Rank	100	500	1000	2500	5000	7500	10000
2018*	Marks (Out of 360)	273	255	240	216	193	177	166

ANNOUNCEMENT

SUPERNUMERARY SEATS FOR FEMALE CANDIDATES –

Recently, a decision has been taken by the IIT Council to provide some supernumerary seats to female candidates, to improve the gender balance in the undergraduate programs at the IITs. 14% reservation for female candidates has been set up in 2018-19, while the ratio at present is a mere 8%.

Please note that this does not mean that seats for non-female candidates will reduce. Supernumerary seats refer to seats above and beyond the usual number of seats. Once all the seats for a program are filled, the percent of female candidates occupying them out of the total will be calculated. If this number is less than 14%, new seats will be created and offered to female candidates on merit basis. The number of seats created will be calculated so as to bring the ratio to 14%.

These supernumerary seats will be offered

(a) to only those female candidates who are declared qualified in JEE (Advanced) – 2018, and,

(b) strictly based on the performance in JEE (Advanced) – 2018.

The reservation applied on normal seats will also be applicable on these supernumerary seats.

The detailed procedure for implementation of the above shall be set out in the Business Rules of the Joint Seat Allocation Authority, 2018.
