I will outline some guidelines regarding CAT which may be helpful to aspirants regarding mocks, resources, test-taking strategies, analysis etc.
For Verbal - Focus more on reading diverse content and comprehend better. Read novels, newspapers, articles etc. Refer websites like aldaily.com, aeon.co, wordpandit.com for content. READING is the key to ace verbal ability section. Practice RCs daily and know your lines of reasoning behind answers to types of questions such as title, inferences, tone, main idea etc. Focus on words like all, some, not, many, most, but, however, etc.
For DILR - Focus on right selection of sets, accuracy, mock to mock strategies of leaving and attempting. Take up national level mock series by CL or IMS or TIME and practice well. Don't increase attempts without accuracy, it can cost huge.
For Quant - Just sticking to basics can seal the deal. Selection of questions is the key here. Identify your strengths and polish them. Work on your weak areas and convert them into strengths. Take more sectional tests here so as to know what you lack from a particular area.
Above all, do not compare your mock scores with your friends and get disheartened. Everyone has different speciality, different strength, a different way of thinking and a different way of performing. Just focus on yourself, improve yourself and stay happy.
