I have been playing poker from past 2 months regularly so my question is how to really improve my game.

1. Dont no how to range opponent (always put them on AJ+ ,TT+)
2. No clue how to play different board texture to be honest I dont no how to recognize it .( I am totally confused)
3. Allin ranges.
   4.EV calculation ( is there any software or its manual calculation)
4. There are lot of stuff to remember how to keep all these in mind while playing .

Any experienced player who had similar experience in the past please comment it will help lot of Beginners

Thank you
