Since you are preparing for CGL , there is roughly just more than 3 months time in your hand. A major portion of this should go practicing questions rather just reading them.
Reasoning: Make a chart and write alphabets A to M in one row and Z to N in the row below. Also write their positional value along with them. It will serve two purpose, first you will learn all the values and second you will learn the alphabets value from the reverse sequence also. Say B is 2nd from the beginning and as you have written Y below B, it will be easier to recall that Y is 2nd from behind. Such type of questions are asked in CGL pre infact around 8 questions are always asked which uses the concept of positional values of alphabets.
When solving a number series question, if the numbers are increasing/Decreasing rapidly keep in mind that some multiplication/Division operation is used in that question else simple addition/subtraction is used. Learn squares upto 25. It will help you solving series and analogy question.
When solving a direction based question, take a look at options before reading question, if the option contains only direction then do not put confusing numerical values when you are making diagram as per the question, It will save time.
Matrix questions usually have option D as correct ( My experience), hence solve option D first.
I never solved questions like, ” ‘-‘ stands for division, ‘+’ stands for multiplication, etc ” because they take a lot of time to solve, if you have time in hand then solve it or move ahead. Same thing for ” how many triangle/squares in this figure”, they will eat your time.
Quantitative aptitude: Learn to practice solving in a single A4 sheet paper.
Do this section in last and begin this section with the questions you are comfortable with.
If the question is unsolved in first attempt, proceed to next. You have to solve “the easy” questions first hence if the question is taking time do not waste time over it.
Do not solve Question complete if you get an idea of answer before hand and make sure you do calculation in fractions and not in percentages.
Here is an example to illustrate these two tips:
Question: The cost price of a table is Rs 3200. A merchant wants to make 25% profit by selling it. At the time of sale he declares a discount of 20% on the marked price. The marked price is?
Answer: Now the book’s method to solve it will be taking marked price as X.
3200*125/100 = X*80/100
X = 5000.
By doing this you would have to do quite a bit of calculation to arrive at the answer.
Now what i did in the examination, I wrote simply “3200*5/4*5/4”
here the first 5/4 is equivalent to 125/100 and second 5/4 is equivalent to 80/100 which is shifted to LHS. The fractions help you to solve faster. If I ask you what is 37.5% in fraction, you should know it that it is 3/8.
Now coming to other tip, 3200*5/4*5/4
cancel 32 by 4 ( always calculate number without zeroes preceding them)
again cancel 8/4. The answer is 2. This 2 is multiplied with remaining 5*5. The answer must contain 5 ( 25*2 = 50), do not THEREFORE solve complete answer just look at the options. I did the same. Hope you understood. 😛
I cannot give much advice here, all you have to do is serious practice.
English: My English is terrible 😀 Just do your basics right. Read my other answers to know about books.
GS: Do not spend too much time learning facts. Learn superficially from any book and leave rest to the destiny.
In the exam hall: Do not use fluid in filling your details or in your answers. This will lead to rejection.
Use Reynold liquiflow pen to fill OMR circles.
I used to mark answers in one go after 90 minutes in the exam.
Best of Luck….happy learning
