How to Prepare For GATE 2018 Within 1 Month Short Time.
1) Take Brief Overlook Of Gate Examination :
Few days back I written about 25 tips trick for preparation Gate examination . You Should well aware about syllabus and question pattern and how marks are divided for each section e.g. aptitude there are 10 marks allocated. This will help you to set study sequence.
2) Starts with your Favorite Core Subject
If you just starting your studies I would suggest first start with your favorite subject which has more weightage or the subject which most important for gate examination , start with it. Most Important subjects for mechanical students are the Thermal engineering , Fluid mechanics ,Machine Design and Manufacturing Processes.
3) Refer previous year gate question paper for particular subject:
Before starting study you should know which points are important and which chapter is most important for gate . This will frame you by analyzing previous year questions papers.
Here I mentioned some important gate topics –Important Gate Topics For Mechanical Engineering
4) More Concentrate on Formulas and Unit Conversion:
This is most important point. You should prepare more for numerical , formulas and related units . If you skip numerical for option or casual then you won’t get good score. You should Prepare for Mathematics, Thermal Examples , Truss Examples, Torsion , Bending Moments , principle stresses, Eigen value problems ,fluid mechanics problems , Machine Design Problems.
5) Prepare Your Formula Book while Studying:
Formulas are most important for us because without knowing formula you can not solve examples. in above mentioned topics you will find lots of formulas , still you have to remember this all formulas correctly . I would recommend you that prepare your formulas book so that it will help you for quick revision in one week before Gate ecam.
6) Use short Notes :
As time is so limited you should go for short notes . We have uploaded some notes and points that will help you little bit:

7) Because Of time limitation you should target specific Subjects. The subjects which has low weightage , you can skip them . The subjects like Industrial Management , Refrigeration and Air Conditiong , IC Engine.
Decide yourself by analyzing Question paper and your Interest.
8) Engineering Mathematics and Aptitude section are Most Important to crack get because it has weightage of near 30 marks if you get here 25 marks ,exam will crack easily.

Some Important Points That Frequently asked In Get Exam:
(1) ENGINEERING MATHEMATICS
This constitutes 15% of the total marks of the paper. Problems on finding rank
of matrix, type of solution (unique, infinitely many etc.), simple
integration (using Trapezoidal, Simpson’s 1/3rd rule etc.), Simple
formula based Laplace Transforms, simple probability distributions
(normal, poisons, binomial distribution , uniform distribution ),
directional derivatives, divergence, curl, simple dice problems, limits,
simple PDE are all common.
(2) MECHANICS, SOM
This constitutes 10-15 marks of your paper. You can find simple FBD problems (just 1) for finding
force, conservation of momentum, block and slope type (average stress
and maximum stress for different sections like rectangle ,triangle
etc.), Macaulay’s theorem (slope & deflection), one question on thin
pressure vessels, problems on various theories of failure , torques,
and bending moment calculation, truss.
(3) DESIGN OF M/C ELEMENTS, TOM
This chapter makes up a huge chunk of your marks – 15 to 20! Expect one problem on (Goodman
or Soderberg or Gerber Criteria), bearings (life) calculation , torsion
of a bar, loading on a plate with bolts, strain energy, S-N curve,
degrees of freedom, output velocity calculation of mechanism, relative
velocity approach, Instantaneous Centre Method, clutch power, brake
power, belt drive, conceptual questions on D.O.F. of mechanisms, simple
gearing ratio problems on spur gears, type of mechanism (based on link
lengths), simple spur gear main, quick return mechanism, mobility.
Questions on vibration account for 2-4 marks. You will find questions on simple single D.O.F , finding natural frequencies (underdamped, critically damped, overdamped)
(5) FLUID MECHANICS
This chapter accounts for 5-10 marks. Expect questions on simple
& differential piezometer, pressure column height calculation,
Reynold’s no. calculation, hydraulic power ,nozzle velocity etc. of
turbines, continuity equation, Bernoulli’s law (simple problems),
tapered sections, pump parameters (speed, power, discharge), gates(of
dams) force calculation, venturimeter , laminar flow.
(6) THERMAL SCIENCE
This is another chapter that accounts for 5-10 marks. Problems asked are usually based on Rankine
Cycle, Brayton Cycle, Regeneration in steam cycles, and other cycles,
T-S diagrams, P-V diagrams, enthalpy calculations, C.O.P., ŋ, parameters
of I.C. engine (power, volume capacity, stroke, ŋ, brake power),
DBT(Dry Bulb Temp.), WBT(Wet Bulb Temp.), ŋ relations (otto ,diesel
cycles), work done, exit temperature in various stages of cycles ,
pressure of nozzle, compressor work calculations.
(7) HEAT TRANSFER
5-10 marks are generally allotted to this chapter. Make sure to study convection,
conduction, radiation, Efficiency calculation, heat exchanger (parallel
& counter flow) outlet temp. calculation, biot number, Prandtl
number, LMTD, Heat transfer through slabs, shells,cylinders, condenser,
view factor, unsteady cooling.
(8) MANUFACTURING SCIENCE
This is a monster chapter. It accounts for 10-15 marks. Expect formula based problems on machining
(milling, drilling, EDM, ECM) machining time, current, tool geometry,
punching, blanking, force; conceptual & theoretical questions;
orthogonal machining , heat & power required in welding,
transformations (rotations, scaling etc.), solidification time, CNC
machine G codes and M Codes , sheet metal, various types of fits,
clearance calculation, arc welding, cutting time ( ) casting Defects.
(9) INDUSTRIAL ENGINEERING
10-15 of the total marks are usually from this chapter. Be prepared with forecasting
model, CPM, PERT, depreciation, cost (labour, tool grinding cost,
waiting cost etc.), P-chart, C-chart, R-chart, X-chart, Time study, EOQ,
standard time, demand, Poisson’s arrivals & departures , LPP
problems (graphical), simplex method, GO, NO-GO gauges, Machine
allocation problems, Sequencing problems , EDD, SPT rule (scheduling)
Use this guide to plan out the next fifteen days of studies. Also, do not forget to prepare for General Aptitude,
which not only carries 15% of the marks but are also filled with
sitters that prove to be scoring. Concentrate on covering high-weightage
+ easy chapters first.
