Hey aspirant, hope you are doing well!

Logical reasoning can be the most tricky part for any entrance exam as it involves presence of mind & high level thinking on the spot. The only way to master any skill or  anything is just PRACTICE. Give n number of mocks for the enhancement of your level. Review your mistakes. Don't just leave a question solved by your teacher or anyone , try it on your own. Practice is the key for gaining accuracy. Start from practicing the simple questions of important topics. Don't just directly jump on the tough ones. Carefully read the questions and then attempt them. Try to convert the questions into charts, daigrams etc. It will make a tricky question seem really easy as it will make it more interesting. Use elimination method on the answers if you can. It will help you focus on fewer options. Don't stuck to one question if you are unable to attempt it , move on to next and after you a little hold on the topic go back to that question again. After doing simple ones , move to the advance level questions which actually come in entrance exams.

Hope it helps! All the best for your future endeavours!
