I would suggest that instead of paying high fees to the coaching centers, you must go on a tour or travel around. If not that, just observe the things around you. Go on a walk every morning and observe the details and designs of the things around. Wherever you go, try to observe and see the things from your perspective. Try to analyses the things and think about them.
Apart from that, try to explore colors and learn about their meanings. For example - yellow color represents happiness and cheerfulness where Violet is for gloom and sadness. Try to connect with colors as the question in these entrance exams are related a lot to these color schemes. Watch Ads on TV. Yes, you heard me right. Questions are asked on that. Read newspaper every day. You not only get to know the news but you English also get improved and English comprises an important portion in these exams.
