Preparation Help
I have looked at your games.
In the first, on move 8 I think d5 is better than 0-0-0. Advancing the d pawn gives you a safe position with a space advantage. Q side castling leads to a dubious version of the sicilian dragon for white.
And certainly your 12th move was a blunder. Had black replied bxc3 you lose a piece.
I would add to squishey's suggestion some endgame study and playing some games at rapid speed exactly as in a tournament, touch move etc.
I will be playing my first rating rapid tournament in may approx 1 month from today. I already have Standard rating. How to prepare for the tournament. I have 3 hours a day for whole april month and then 6 day I can spend as much time I want. So how to should I train my self to get a good rapid rating. [Because for my rapid rating my standard rating will be taken as base so].
Any help will be appreciated/
I will also sumbit my 2 games so guys you can help properly
