Yes you can. It is ‘not impossible' to study for CS-Foundation in a month's time. I myself prepared for CS-Foundation in a month on my own and secured AIR. So here are few tips which I followed myself.
Take a module and go through its index to get an idea about what that subject contains. For example, if you take the business economics module, go through its index. By this you will get an overall idea about the topics covered in it.
Mark the topics which you think you have some knowledge about it. In Business economics, there will be chapters on topics such as demand and supply, diminishing returns etc. which you might have studied in your high school if you are a commerce student. Mark them because these are such topics the concepts of which you already know; you just need to revise it. Also marks topics about which you have no idea . Try to read these topics first as it will consume more time. Thenafter, read the known topics.
Use menemonics, memory maps, flow charts etc. to understand and retain the concepts. Write them down in a separate book for each subject. Writing down the concepts etc. will help you to retain for a long time. [ If you are that person who is lazy to write in a separate book, write the concepts in brief in the margin of your module where the topic is situated.] P.S. whether you are lazy or not writing in the margin really helps when you are doing a last minute revision.
While reading the chapters, mark lines and words which you think are important and can be asked for mcqs. You can use different coloured pens to mark the important points. Use sticky notes as well. This can work as a flash card for you.
Basic Law has been introduced in the foundation course. This is new and legal jargons are used so it generally take more time than the rest subjects. Devote more time to it. Topics such as Contract Act, Sale of goods Act, etc are important and it is necessary to understand the underlying concepts thoroughly. These acts, if concepts are very clear, can help you to fetch more marks.
Time period for each subject:
Business environment and entrepreneurship: 10 days
Business management, ethics and communication: 6–7 days
Business economics: not more than 6 days
Fundamentals of accounting and auditing: 6–7 days
Note: the time period is tentative.
7. Also you should keep in mind that at least you should read two modules per day. This will help you to not get bored.
Practice Accounts daily. Auditing is a new topic, try to read it daily.
8. Don't procastinate.
Believe in yourself.
Study at that time which suits you the best.
Avoid any kind of distractions like WhatsApp, Facebook, etc. your friends can live without you for a month.
