Data science is a broad topic. It can be divided into many parts like data analyst, machine learning, artificial intelligence etc. It also requires good knowledge of statistics.

The best way to start this journey is to pick up a programing language like python or java or R. You can also learn data analysis in MS excel or MS power BI. But picking up a programming language will always give you flexibility to scale up your knowledge. Then learn different steps of data analysis first. Then try to apply this knowledge on Complex data. You can get the data sets online. Then learn machine learning I.e basically analytics part with seral tools. This will take quite some time. After that you can move onto advance stage.

There are three types of chemical bonds. In the case of covalent bond, electron sharing takes to obtain the electron structure of the nearest inert gas in the periodic table.
Carbon has four outer shell electrons. So it can form 4 covalent bonds with other atoms. So, CH4 is the simplest organic carbon compound.

Firstly you need to understand that you need to set up your goals and then develop a strong foundation accordingly. Because nowadays everybody looks for experts. So take your time to clarify the fundamentals, then definitely try to correlate with something (In case of science subjects). Practice it regularly, solve problems as many as possible.

And make a suitable schedule for yourself because time is short.
