    Hello @fatimidveil

    100% accuracy is something one should be very careful about. You need to check a few things listed below.

    1. Label leakage: If your data set is time-dependent (temporal characters), using regular validation methods like cross-validation is not recommended. 
    2. Highly correlated column: If your dataset has an attribute that replicates output, then there is a chance of getting 100% accuracy.
    3. Validation Type: If you are using something like a split validation, there is a chance that you might get very high random performance.
    4. Size of a dataset: If your dataset is too small and you have a very small test set, then you can get very high performance by chance.

    These are some points in my mind right now, will update if I get more.

    Be Safe. Follow precautions and Maintain Social Distancing
