The above areas describe comprehensively the most important and in-demand knowledge areas and skills needed as Data Scientists.You may learn them at your pace and in different combinations and get Data Science related jobs of different levels. Important thing to note is that you do not have to master all levels at same time and can began small and step-wise. Later you can also specialize in one area/technique and become a domain expert in that depending on your interest and capabilities.

However having good foundation in Statistics is essential to progress in this field so you do need to get your concepts cleared in that.

After that as they say ‘Sky is the Limit’ and you can grow exponentially in the field . You will be able to help organisations grow , analyse world situations through data , minimize uncertainties & risks and even design innovative AI solutions to help business and human welfare. If you wish to check your suitability for this field , you may take our Data Science Aptitude Test. You may also check out our courses to know the Data Science Series path you can take to make a career as a Data Scientist and you can also talk to our Consultant in a One one One session to check if these programs are relevant for your aspirations and career goals.
