There are four sections in SSC CGL namely
1.General Intelligence and Reasoning
2.English Language
3.Quantitative Aptitude
4.General Awareness
Coming to clearing SSC CGL if you have prepared earlier for any other competitive exams you would have gone the syllabus once.But if that is not the case you have limited time here.
For the first part, i.e. Reasoning the best approach would be to go through the syllabus once get a rough idea of each type of problem and try to solve at least 2 or 3 problems of each type them.Because it is very necessary to learn how to tackle these type of problems and you should have some prior knowledge about each of them as every problem is a variation of its basic premise.
For the second part, i.e. English Language If you are an above average reader you would be able to handle it. It's not that tough and can be easily handled. If you struggle in English and do not have a good command on it the best way would be to read as much as you can till the exam as only reading will help you to get a sense of English.Try to increase your vocabulary by reading English newspaper and especially the editorial it helps in increasing your vocabulary and also helps about a how an idea is presented.
For the third part, i.e. Quantitative Aptitude this part is a tricky one. Firstly you have to cover all the formulas and understand their implementation in the questions then you will have to work yourself up to the level of question and here also try to every type of question as each type of question uses a different concept.
For the fourth part, i.e. General Awareness the GA part has a question from everything which you have studied till now from your childhood. It has questions from history, geography, economics, biology, physics, chemistry, general studies and current affairs.The current affairs part can be learned from any site which provides daily updates on ga.
Finally, some points to give you a scenario on how to get things done
- Give a mock test to know your position what you know and what you need to improve(Mahendra's test series is a good option)
- Work your way to remove the problems which you have dealing with specific sections.
- Try to cover every type of question
- Slowly try to increase you're no. of attempts
- Only mark those question which you have got the exact answers for in QA and Reasoning.
- DO NOT LOSE HOPE because“Everything is going to be fine in the end.
- If it's not fine, it's not the end.”
