# How to Prepare Electrical Engineering for GATE-2018

This post focusses on How to Prepare Electrical Engineering for GATE-2018

The (Graduate Aptitude Test in Engineering) GATE-2018 will be held in the month of February-2017. This time the exam will be organised by Indian Institute of technology IIT-Roorkee. The Exam is conducted all over India for Engineering and Science graduates for entrance to Post graduate courses. Furthermore the Public Sector Units (PSUs) also select candidates based on their GATE score.

The Gate Examination is conducted in 23 branches codes  as mentioned below AE, AG, BT, CE, CH, CS, EC, EE, IN, ME, MN, MT, PE, PI, TF and XE AR, CY, EY, GG, MA, PH and XL

Well in this post we will discuss important strategies to crack GATE from Electrical Engineering and Electrical and Electronics Engineering Branch and How to Prepare Electrical Engineering for GATE-2017 . Also  Candidates with various correlated branches have to appear GATE from Electrical Engineering only.

First of all, Lets discuss the pattern of GATE Exam -2017. There will be 65 Questions to be attempted in Duration of 3 hours. There is also the provision of negative marking i.e .33 marks and .66 marks for 1 mark and 2 mark questions respectively. Below is the exam pattern in Tabular form-

 Section No. of Question Marks per Question Total Marks General Aptitude 15 1 15 Electrical Engineering &Engineering Mathematics 50 1 & 2 Marks 85 Total 65 100

Note- There will be Numeric type questions also in which candidate has to fill their responses. 25-40 marks allotted for such questions. These questions have no negative marking.

Going through syllabus is very important. One should have an idea of which topics to excel and which topics to skip. This helps  in selective study to prepare of exam. Here are some strategies to have an edge on preparation and How to Prepare Electrical Engineering for GATE-2017. Therefore,  adopting these strategies will make preparation smooth.

1) First of all go through the detailed syllabus of Electrical Engineering. Select the subjects accordingly.

2) Focus more on core subjects. For Electrical Engineering Power Systems, Electrical Machines and Power Electronics are must. These subject carry more than 50% of Weightage of  Technical Subjects.

The Priority of Subjects should be –

• Power Electronics
• Machines & Drives
• Power Systems
• Control & Automation
• Digital Signal Processing
• Instrumentation Technology

3) Prepare good notes using Standard textbooks like C. L Wadhwa, PS Bhimbra etc. or get enrolled in good coaching if self study is not possible

4) The Most important factor is “Previous Years Questions”  . Do Practice these previous questions as much as possible. This will help you get an Idea of level of Questions asked in the exam .

5) Make a short note for Various Formulae asked in the technical section.

6) Practicing Mock Test is another Important pillar of preparation. Stick to good test series. This nourishes our preparation and helps to experience Real time exam mode.

7) Consistent revision of subjects help in mastering the subjects quickly.

Best of Luck of Exams!!

5. garcinia cambogia weight loss pills walmart says:

To air on the safe side, avoid purchasing garcinia cambogia formulas
or supplement mixes,” which might neglect to report all the other fixings precise or included amounts of
HCA.

6. Stephen says:

You probably will not need to buy it there although you can now locate Garcinia Cambogia in vitamin stores
and department stores.

7. Alfonzo says:

Do not be fooled by products labeled as Garcinia cambogia
extract standardized for (—)-Hydroxycitric Acid, which tag only the
number of Garcinia, and not the amount effective (—)-Hydroxycitric Acid.

8. garcinia cambogia dr oz amazon says:

Medications and the prescribed drugs may be used with this extract only as recommended
by the medical practitioner to make your dose work wonders for you.

9. Sheldon says:

The finest brand available on the market must
always have a GMP certification to ensure that your nutritional supplements
are safe for daily consumption and successful for its weight-loss benefits.
