Exams can really be very stressful, especially professional exams or higher educational exams. But don't worry, i am here to help you out; so that you wont have any stress during or before your exams. 

1] First things first, you should complete each and every topic taught in the class, on the same day. this may be hard but this really works especially for professional exams like chartered accountant, association of chartered certified accountants, etc….. BE CONSISTENT.

2] Start making notes. use colorful pens, sticky notes, highlighters etc…decorate your book in such a manner that you  must be keen to study. notes should consist of important points, new concepts, most likely questions to be asked, tricks to understand. notes are really very important. when there are only few days left for the exam, you just have to keep on reading notes rather than reading the whole book. in this way you wont be able to miss out any concept.

3] Search for questions related to your topic from google or from your text-book. Ask yourself some questions. solve those questions and examine your marks, your mistakes, go through the papers and note down things you feel are important. solve those questions once again with proper understanding and technique. 

4] Read and act according to your study guide. complete each and every topic mentioned in the study guide and question yourself. learn or understand those chapters or lessons in such a manner, that you should be able to teach others. 

5] Make a separate book and note down all your weak chapters or areas and start working on them. spend more hours on areas that may become the reason for your failure. watch online videos related to that chapter or area, in this way your concepts are cleared. note down all the necessary details.

6] Avoid social media or any distractions. always remember one thing, ‘once an excuse, always an excuse’. stay focused, note down your dreams on a piece of paper and stick it on your board, this will motivate you to be the person you are dreaming to be. 

7] Before a month or so, you will be done with all your chapters, notes, questions, concepts etc…now you only have to revise and revise. go through all your notes, questions, weak areas, memorize topics, and you are done. 

If you follow this method i can assure you, you will be able to pass any exam on your first try.
