How Do I Get Data From A Txt File Which Contain First Name, Last Name, Test1 Marks, Test 2 Marks And Calculate The Grade A Students Overall Average Like That

you havnt provided enough information for us to be able to fully suggest an approach - for example, is that information on each line, separated by commas for instance ?

I would

1) Write a program to read a text file, line by line, and simply output to the console each line as its read
2) when (1) is working, then, once you've read each line (and assuming the data is separated by commas ie ','), split the line into fields - write each field to the console

3...n depend on what else you need to do to the data

obviously, comments, error handling, closing the file ...
