In window 11 you can easily split by howering mouse on minimize/maximize but if you are using window 10 or earlier version then u can also split but not easily.you will do by dragging mouse.
You will minimize your browser then adjust by clicking left mouse button on the right, left, top, bottom or whichever side of browser u want to adjust. Then set width and height according to your need of any application or browser. Dont leave left click button until size don't get adjust according to your need.
Ye to karne wale pe depend karta.we can just guide someone but it does not mean that everyone will get same output.i said how can u get full marks and tell the way.i didnt say that if u will do this u will must get and this is my guarantee.
Then why did u try this method after knowing this?there are many who dont even get 3 or 4 marks but i am helping others and they are getting more then 3 or 4 and they are happy.
