Hello@Aaadi

Are you tuning your model hyperparameters? Are you extracting relevant features from your data so that they add value to the model? Did you try different models?. There are multiple things you can look at to improve your model performance. You should also look at the type of validation you are using, are you doing a split validation or cross-validation? If split, then this high performance might be based on random chance. You need to provide more information about the problem you are trying to solve for us to provide appropriate recommendations.
