Commerce

Here are some courses mentioned-
1. Computer Courses: Basic computer knowledge with an average typing speed is a must to obtain any job in these days. The computer has become an essential part of our life and one who is unaware of the basics of the computer will be pushed back by other candidates. For a commerce student, minimal computer knowledge will be enough. You may attend courses on Microsoft Office (MS Word, MS Excel, MS Access (SQL) and MS Power Point). Among these MS Excel and MS Access will turn out to be important. Still, there are many calculations and information stored in MS Excel by organizations, hence a thorough knowledge of it is a must.
2. Accounting Software: Gone are the days of bookkeeping. Now everything is stored in a system and to make it much easier, accounting software was developed. There are many popular accounting software such as Tally, Peach Tree etc. An organisation can develop customized software also. If you are commerce graduate or postgraduate and would want to have a strong career in the accounting field, then you must learn any of the accounting software and must obtain a certificate from an approved institution. The important accounting software normally used by companies are Tally, Peach Tree, QuickBooks Pro, MYOB Business Essentials Accounting Software, etc. Always make sure to learn the latest version of the selected accounting software.
3. SAP/ERP: SAP Enterprise Software is used only be few companies, especially by MNCs. ERP (Enterprise Resource Planning) is another term we hear these days. Yes, these two concepts are of great importance and a person with knowledge of these two can get better job opportunities. There are not many who have done this course, hence your chances are more. The duration of the course varies from 45 days to three months.
4. Advanced Certificate Course: SHRM (Strategic Human Resources Management) India, Carlton Advanced Management Institute, The Indian Institute of Technology (IIT), Bombay, Sales and Marketing Executives International (SMEI) etc. are some of the establishments that offer good and authenticated certificate courses for commerce students. If you are looking for an advanced certified course in the field of finance, then you may go for Certified Financial Planner Course (CFP). It is a course by Financial Planning Standards Board of India.

The answer is simple, but the journey isn't. Here are the two possibilities:
You climb the ladder : This the process that most of the CEOs follow. Like Satya Nadella, Sundar Pichai, etc. They all climbed the ladder. They joined the tech giants during the early stages and due to excellence performance they were promoted over the years and finally to the position of CEO. Not all get the chance, to be like them you have to be unique and possess good leadership skills. Being a CEO is not easy job. You should be able to take the mental pressure, handle the entire company and manage 100s of resources. This takes time and required patience and dedication
Build your own ladder : This is way how Elon Musk became SpaceX's CEO, Bill Gates became Microsoft CEO or Mark Zuckerberg became Facebook. All you need is one in a million idea that will affect the world and you will change lives of many. You have to create a product/service that people will love. Start a company, work hard towards it and grow it bigger. Also, leadership skills are important. You should be a brilliant salesman that can sell anything to anyone. Build an empire and work hard towards it. Be a CEO of your own company
These are two best ways to become a CEO.
