TIPS for QUICK ANSWERING in a MCQ test

From years of experience, the short list of tips for accurate and quick answering compiled.

You,

1. Must have a good understanding of the BASIC CONCEPTS of the topic.

2. are ADEQUATELY fast in mental math calculation: For SSC CGL lighning fast mental calculation NOT NEEDED at all.

3. Should FORGET USING TRICKS. Instead, first use basic concepts and then advanced concepts created from basic concepts. Identifying key patterns in a problem is vital for quick solution.

4. DO NOT MEMORIZE formulas. Practice solving many SELECTED problems, if needed REPEATEDLY, to know by heart how to identify the key patterns in the problem and take the action for solving the problem quick and correct.

5. WRITE DOWN the most used concepts and formulas for solving algebra McQs in two sheets of paper (try to be short because it is for yourself). This writing down will help in recall when you need. You will get PRACTICALLY ALL FORMULAS AND TECHNIQUES NEEDED FOR SOLVING ALGEBRA MCQS IN SSC CGL in Suresolv. Go through the articles at your pace using the links in Guided help on Algebra in Suresolv.

6. DO MOST of the REASONING IN YOUR HEAD without touching pen on paper. Make it a habit during practice sessions. If needed repeat a test of 10 algebra mcqs.

7. Go through the most used algebra problem solving FORMULAS AND TECHNIQUES in Basic and rich Algebraic concepts for elegant solutions of SSC CGL problems.

Set the timer ON and take the test now in all seriousness.
