#### How to prepare

**Preparation Strategy**

**Make a proper Time Table**

It is very important that you ** make a time table and stick to it** and you will have an exact idea of what you are required to study and the time required for it.

**Concept clarity rather than rote learning**

It is essential that you have a clear idea of the ** formulas and concepts** rather than rote learning of things for the papers. While you might require it for memorizing formulas it is important that for other stuff you make sure you

**before moving on.**

**clear your basis and concepts****Prepare Notes**

It is very important ** make small notes** or a

**each covered topic and chapter which will come in handy at the time of revision. This will require you to be regular with your work but will surely make things easy at the time of revision.**

**comprehensive list of formulas on****Revision of Class XI and XII concepts**

Make sure that you ** revise your concepts from the syllabus** of these classes before starting anything new as most of the engineering exams will be for admission to undergraduate courses and so the

**syllabi from class XI and****becomes the testing ground to check students.**

**XII****Seek guidance**

It is not possible for you to know everything in your syllabus, at least not at the time of preparation. Sooner or later you will run into a concept or so which will give you trouble and then it is best you seek guidance from an instructor or a teacher. It is necessary that you clear your doubts at regular intervals and don’t prolong things for long. Getting into a good coaching class is nothing to be ashamed off and if anything a regular coaching class will enable you to avoid roadblocks in your preparation.

**Sample Papers**

Even though there may be a complete change in the exam pattern or the expected questions altogether,it is important that you practice on the sample and previous years question papers available for the engineering exam you’d be attempting. You will know the existing pattern and have a fair idea of the type of questions to expect in the paper along with the time constraint.

**Mock tests**

The paper pattern, duration of the paper and the number of questions to be attempted in the given amount of time is not something you will be able to pick up on the day of the examination. A Mock Test tests a student’s abilities as it not only provides a similar feel of real exams but also helps in building speed and confident to face the exam. Furthermore, they can improve their performance to get an extra edge in actual exams. Try to build up an Engineering Entrance Exam Test Prep MCQ Question Bank

**Time management**

Time management can be learnt through thorough practice and regular test taking. So it is important that you practice it and practice it well.

**Negative marking**

Most the entrance examinations will have negative marking and everyone would suggest you stay clear of questions are not sure about. But some experts are of the opinion that you answer the questions in which you are confused between an option or two because there will also be a chance of getting it right.

**Duration :**2 Hours

#### Important Instructions

Candidates applying for the courses should submit separate applications for each stream with necessary Xerox copies of the certificates. Application fees should be paid only through on-line (Credit cards/Debit cards/NEFT). No other option is provided. Payment details will be provided in the CENTAC website www.centaconline.in Candidates are asked to submit the latest/updated certificates, particularly the Residence and Community certificates. Certificates once submitted are the final and further changes/modification would not be entertained. Candidates having the Permanent Integrated Certificate (PIC) should update their certificate from the Revenue authorities at the time of submission of the filled applications, if not it will be rejected. Special categories like Freedom fighter (FF) and Wards of Ex(service man)/Physically challenged (PH) should produce the latest certificate from the concerned authorities. For example, FF from Freedom fighters cell, Ex-service man certificate from Sainik Welfare board and PH certificate from the Medical Superintendent, Government of General Hospital. Options once exercised with regard to course/community/region/special category shall not be changed under any circumstances.
