International biology Olympiad

5-STAGES EXAM

STAGE:-1 NSEB

 (National Standard Examination in Biology).

Introduction:-

NSEB is the stepping stage for selection of aspiring and talented students in the Biology Olympiad Program. The student can move forward to other stages only after clearing this stage.

 Eligibility:-

 Only Indian citizens born on or after July 1, 1996 and are students studying in Class XII, can apply and appear for NSEB. The student has to himself re-assure his eligibility. At any stage if the student is found to be not eligible for the exam, he/she may be disqualified from the program.

Syllabus:- 

The syllabus for National Standard Examination in Astronomy (NSEB) is almost similar as the curriculum of senior secondary level (Class XI and Class XII) of CBSE. However, only basic guideline for the course is mentioned. No detailed syllabus is given for NSEB. There is greater emphasis on Botany and Zoology.

Question Paper:- 

The medium of test was English only and it comprised of 80 objective type questions, each with only one of the four options correct with 3 marks each and -1 negative marking for incorrect answer.

 Qualifying for the Second Stage:- 

The basic objective of conducting this test is not focusing on merit but to involve as many students from the country to participate in the exam and try to show and expose their talent. Hence the selection to the stage II examinations i.e. Indian National Olympiad Examinations (INOs) is based on the following scheme.

Cutoff:-

  • To be eligible to get to the next level, i.e. the second stage, it is necessary that a student scores at-least a Minimum Admissible Score (MAS) which is 40% of the maximum score.
  • Proportional Representation Clause:
  • The maximum number of students that can get to Stage II (INO) in each subject is around 300. These many students are not selected only on the merit basis but also on proportionate basis.
  • This proportion is decided on the base of the number of candidates who appeared for NSE in the previous year from that center in each State or Union Territory (UT).
  • In case there is a tie at the last position, then all the students competing for the last position will be eligible to move to stage II. However it’s necessary that the selected students fulfill the eligibility clause laid out above. The total number to be selected from centers in each State for each subject will be displayed on the IAPT and HBCSE website.

 Minimum Representation Clause:-

  • Notwithstanding the proportional representation clause the number of students selected for INO from each State and UT must be at least one, provided that the eligibility clause is satisfied.

Merit Clause:-

  • As stated above, approximately 300 students are to be selected for second stage. If this does not happen according to MAS, then after selection as per merit, the shortfall from 300 students will be selected based purely on merit without further consideration to proportional representation and minimum representation clauses.
  • In the event of a tie at the last position in the list all students with the same marks at this position will qualify to appear for the Stage II examination.

There will be no other criterion or provision for selection to the Indian National Olympiad Examinations (INOs). All students who qualify to appear for the INBO get a certificate of merit from IAPT.

Overall Marks Distribution:-

The paper pattern was same as last year. The paper had 80 questions each worth 3 marks. All questions were objective type with single correct option.

Expected Cutoff

To be eligible to get to the next level, i.e. the second stage, it is necessary that a student scores at-least a Minimum Admissible Score (MAS) which is 40% of the maximum score.

Stage II:
Indian National Biology Olympiad (INBO)

The aim of the first stage examination is to have a wide reach, to progressively increase this reach and to attain nationwide representation for Stage II without overly compromising on merit. Hence the selection for the Stage II examinations i.e. Indian National Olympiad Examinations (INOs) is based on the following scheme.

Eligibility Clause:

  • To be eligible for the Stage II INO exam leading to the International Olympiad, a candidate must secure a score equal to or greater than a Minimum Admissible Score (MAS). The MAS for a given subject will be 50% of the average of the top ten scores in that subject rounded off to the nearest lower integer.

Merit Index Clause:

  • There will be a high score called the Merit Index (MI) associated with each subject in Olympiads.
  •  The MI in a subject is defined as 80% of the average of the top ten scores in that subject rounded off to the nearest lower integer.
  •  All students with a score greater than merit index MI for the subject will automatically qualify for INO Stage II examination in that subject.
  • For example, if the average of top ten scores in a certain subject is 92, then 80% of this is 73.6. Then the MI in that subject will be 73. All candidates with a score equal to or above 73 in that subject will automatically qualify for INO stage II.

Proportional Representation Clause:

  • Students from all States and UTs need to be encouraged to appear for the first stage examination and a nationwide representation for INO Stage II is desirable.
  •  The quota for each State/UT used in National Talent Search Examination (NTSE), a nationwide competitive examination will be used as the baseline for calculating the number of students qualifying for Stage II INO in every subject from centres in that State or UT.

Suppose the NTSE quota is S for a State, and the total for all States and UTs is T, then the total number of students to be selected to INO Stage II from that State would be S/T times 300, rounded off to the nearest higher integer.

 This number will include those selected on the basis of the Merit Index. In the event of tie at the last position in the list, all students with same marks at this position will qualify to appear for the INO Stage II examination.

 The selected students must nevertheless satisfy the eligibility clause. The number to be selected from all the centers in each State or UT will be displayed on the IAPT and HBCSE websites.

Minimum Representation Clause: 

Notwithstanding the proportional representation clause the number of students selected for INO from each State and UT must be at least one, provided that the eligibility clause is satisfied.

The above criteria are illustrated with the following examples:

  1. Let the quota on the basis of the Proportional Representation Clause (c) for a State S1 be 20. Suppose the number of students satisfying the Merit Index Clause (b) in a subject is 10.
  2. These 10 students will qualify for the second stage INO exam in the given subject and an additional 10 students from the State S1 in the given subject will be selected merit-wise, provided they satisfy the Eligibility Clause.
  3. Candidates who have represented India in the International Olympiad on a previous ocassion (IPhO, IChO, IBO, IOAA and IJSO) need not appear for the first stage NSE examination in the respective subject.
  4. Those candidates who thus qualify to skip the 1ststage NSEs may be allowed, on written request, to the respective National Coordinator, to directly appear for the second stage Indian National Olympiad (INO) examination, provided they satisfy other eligibility criteria such as age, pre-college status, etc.
  5. There will be no other criterion or provision for selection to the Indian National Olympiad Examinations (INOs).
  6. All students who qualify to appear for INBO get a certificate of merit from IAPT. For any queries or clarifications and for any difficulties regarding enrollment for NSEB, please contact:

 INBO is organized by HBCSE at about 15 centers in the country.

 The confirmed date and schedule will be announced in the first week of January  on the website and communicated by post to the eligible students. 

 Students appearing for INBO are eligible for TA/DA as per norms of the programme.

Syllabus :

  • The syllabus for INBO is broadly similar to NSEB. The syllabus, however, is only a broad guideline. Questions and problems in National Olympiads are usually non-conventional and of high difficulty level, comparable to International Olympiads.
  • On the basis of performance in INBO, the top 35 students in the merit list are selected for Stage III Orientation Cum Selection Camp (OCSC) in biology.
  • In the event there is a tie at the last position, all students with the same marks at this last position qualify for OCSC.
There will be no other criterion or provision for

Selection to OCSC.

Stage III: Orientation  Cum Selection Camp (OCSC) in Biology

  • OCSC in biology will be organized by HBCSE sometime in April to June 2014 for 2-3 weeks. The precise dates will be announced prior to or along with the announcement of the selection list for the OCSC.

Eligibility for OCSC :  

  • Only the students selected from the merit list of Stage II (INBO) are eligible. There will be no other criterion or provision.
  • The camps include several theoretical and experimental tests.  Orientation is provided to students especially in experiments. The camps conclude with a valedictory function where distinguished scientists are invited to speak to the students.
  • The merit list of OCSC is prepared on the basis of the combined theoretical and experimental score aggregated over all the tests in the camp, with 60% weightage for theory and 40% weightage for experiment. Performance in previous stages (NSEB and INBO) will not be a consideration for the merit list and awards of the OCSC.
  • The top 4 in the OCSC biology merit list are declared to be special merit awardees. These special merit awardees are given Rs. 5,000/- each in the form of books and cash. In addition there are special prizes to recognize meritorious performance in theory and experiments.

  • The 4 special merit awardees in biology selected at the end of the OCSC constitute the 4 member student team for the International Biology Olympiad (IBO), provided they satisfy required criteria such as age limit, holding valid Indian passport, medical fitness, parental consent, etc.

Stage IV: Pre-departure Training (PDT) Camp for IBO

  • The selected 4 member  Indian team undergoes a rigorous training programme at HBCSE in theory and experiment. Special laboratories have been developed at HBCSE for the purpose.
  • Resource persons from HBCSE and different institutions across the country train the students. The duration of training will be subject to IBO regulations.

Stage V: Participation in International Biology Olympiad (IBO)

  • The 4-member student team, 2 teacher leaders and 1 scientific observer constitute the Indian delegation to the International Biology Olympiad (IBO).
  • The 25thIBO was held tentatively in Denmark from 12–19 July 2015.
