Dear Priya, first off to be eligible for NEET, you should have completed your 10+2 and scored an aggregate of 50% in Physics, Chemistry and Biology. It is 50% for General Category, 45% for PWD and 40% for OBC,SC,ST. Now once you appear for NEET, the cut offs will be released. Though cut offs change every year, cut offs are dependant on various factors like no.of candidates appearing for the exam, no.of candidates qualified, top NEET score and difficulty of the exam. In 2019, the cut offs went higher by 15 marks from 2018. It is yet to be known what might be the cut offs for 2020. Now mere securing cut offs cannot get a Medical Seat. In 2019, the cut offs went so high that Cabdidates with 550 and above score had to be satisfied with a MBBS seat in Private Medical College. Again, against some 60,000+ MBBS seats across India in 2018, the number increased to 90,000+ MBBS seats is 2019 and 5,200 seats being accomodated to EWS reservation. Now talking about Categories, its just not your score but also your Category that plays a role in your name showing up on the merit list. As of now the reservations that are in place are:
OBC: 27%
EWS: 10%
SC: 15%
ST: 7.5%
The remaining reservations like PWD,  Sports, Women Category, Ex Servicemen and Defense, Victims of terrorism, etc are available at Horizontal level at the respective State Counsellings. Now we all also have 2 levels of Counselling. Under All India Quota, All the 15% of All India Quota Seats except for Jammu and Kashmir, 100% Seats at Deemed and Central Universities, IP Quota seats in ESIC Colleges, Seats at AFMC are filled by DGHS. The 85% State Quota and Private Colleges are filled by the respective State Authorities. So each college has a different cut off for All India Counselling and State Counselling for different Categories. Now NEET 2020 dates have been released by NTA and they have been mentioned here for you:

Registration Dates: 2nd to 31st December, 2019
Downloading of Admit Cards: 27th March, 2020

Dear Sushma, we shall be honest with you. There are 20 IIMs and each IIM has its own selection criteria abd almost as many as 1000 Participating Institutions. The calculation and weightage of marks given for Academic section is different for each Category. And then each IIM Categorises and defines sectional importance in CAT exam differently. You havent mentioned your target Institutions. For example, look at this:

IIM                          QA              DLR        VARC      Overall
Ahmedabad          65               65               65            70
Bangalore             70                70              70             75
Calcutta                65                65              65             70
Indore                   70                 70              70             80
Lucknow              77                77               77             82

And once these scores are calculated, the following formulae are used to calculate your 10th, 12th and Graduation scores:

10th Standard: 36*[Z Candidate-Z min/Z max- Z min]


12th Standard: 40*[Z Candidate-Z min/Z max- Z min]


CAT 2019 score: 20*[Candidate's overall score /Highest CAT score]


Gender Diversity Factor: = 4 for female applicants


=0 for other applicants


Composite score= sum of the above scores

And with CAT being conducted in 2 different slots, there should be a way to commonise the CAT score. The scores will be normalised to ensure equivalence in the difficulty levels of the exams for both slots. IIM Kozikhode will normalise the CAT scores using percentile equivalence. Adjustment of location and scale differences of score distributions across different norms and then scores will be normalised. These scores will be then converted into percentiles for shortlisting and selection purposes.

And your Graduation stream plays an important role in adding marks to the Academic Diversity Factor. For example for Commerce stream, the calculation is as follows:

Percent Scored         Rating Score
<=50                                 1
>50 and <= 55                2
>55 and <= 65               3
>65 and <= 75              5
>75 and <= 90               8
>90                                10


For Graduation, the percentage of marks secured will be considered final. If the Institution doesnt grant marks but grants grades or percentages, it will be calculated on the basis of marks obtained in the marks list.

That will be calculated as follows:

Percent Scored            Rating Score

<= 55                                      1

> 55 and <= 60                     2

> 60 and <= 62                     3

> 62 and <= 65                      5

> 65 and <= 70                      8

> 70                                         10


For Science Stream, the calculation is as follows:

Percent Scored               Rating Scored

<= 55                                           1

> 55 and <= 60                          2

> 60 and <= 70                          3

> 70 and <= 80                          5

> 80 and <= 90                          8

> 90                                            10

Now coming to Graduation in Science Stream, the calculation
is done according to the following table:

Percentage Scored          Rating Scored

<= 55                                              1

> 55 and <= 60                             2

> 60 and <= 62                             3

> 62 and <= 65                             5

> 65 and <= 70                             8

> 70                                               10


The minimum cut offs in 12th in Science Stream across all Categories have been as follows:

General Category: 80
OBC-NC/Transgender: 75
SC:70
ST: 65
PWD-UR/OBC/TG/SC: 70
PWD- ST: 65

And the final score is calculated using this formulae:

Personal Interview Multiplication Factor = 0.50
AWT Multiplication Factor = 0.10
CAT Score Multiplication Factor for Final Composite Score = 0.25
Application Rating Multiplication Factor for Final Composite Score = 0.15

So based on your Category, to get a call from an IIM, you score should be as follows:

General Category: 98+

OBC-NCL: 90+

SC: 75+

ST: 65+

However if your target is to get into a normal to good  MBA College, you should aim at atleast 85%.

Dear aspirant,
Yes gate score and marks are valid for 3 years. Gate score is used to get admission in IITs. Hope it helps you.
Thank you.
