IOQP-Indian Olympiad Qualifier in Physics

Indian Olympiad Qualifier in Physics

IOQP-Indian Olympiad Qualifier in Physics

One of the few exams at the school level that examines students' intellectual and experiential learning of Physics is the Indian Olympiad Qualifiers in Physics (IOQP). As a result, studying for the actual exam becomes harder. And one of the simplest but most effective and efficient ways to boost your preparations and see where you stand among your peers is to solve sample problems.

Instead of three phases, the national Olympiad programme in science topics will now follow a two-stage selection method that will culminate in the international Olympiads in 2021.

• The first stage will be the Indian Olympiad Qualifier (IOQ) in 2020-2021.

• The second step will be the Orientation and Selection Camp (OCSC).

Orientation-cum-Selection Camps Selections (OCSCs)

Unless announced otherwise before the IOQ examinations, a total of 35 students will be selected for OCSC in Biology, Chemistry, and Physics, and 50 students will be picked for OCSC in Astronomy.

If there is a tie at the final position in the respective IOQ Part II merit list, all students with the same marks at the last position shall be eligible for the OCSC.

Preparation Tips For IOQP

When preparing for the Olympiads, you must keep a number of things in mind. You'll be competing against the finest in the country. Here are a few pointers to assist you with your planning:

Start Your Preparation Right Away

Waiting until the last minute to prepare for the Olympiad is not a good idea. To achieve the finest results, you must plan ahead of time. Only if you are committed to succeed will you be able to pass the exam. You can concentrate better if you have ample time.

Pay Attention To The Syllabus And Exam Pattern

Don't forget to look over the exam schedule and syllabus to obtain a better understanding of the Olympiad. For preparation, look at the marking scheme, amount of questions, and themes.

Have a Time Table

Managing your time is critical to achieving your objectives. Allocate a specific amount of time to each subject. You must keep to the schedule until the syllabus is finished. The proper separation of time will aid in the avoidance of any ambiguity.

Assemble all of your resources

Gather all of your resources before you begin your preparation (online and offline). You will not squander any time if you have the right study materials.

Work on your ideas

You can solve any question linked to it if your concepts are clear. Prepare a few short notes to help you grasp the concept of the topic.

Attempt to solve sample papers

You should solve a lot of example papers to measure your preparation because they will assist you identify your strengths and shortcomings.

Be Consistent

Nothing will aid you in acing the exam more than your constancy. Maintain a regular study schedule. Set a specific goal for the day and complete it within a specific time frame.

Best of luck to all of the candidates. Above all, have fun with the Olympiad because sometimes the journey is more important than the destination. For other such details check our website.
