Thanks :)

This is strange because in competition ppl try many things and when we test the trials, we are only pushing the submission file without the code. So I feel like it will be difficult to remember on which trial, what changes I made :D

You will have to keep track of all your submissions and solutions. There is no other way. 😊

your rank will be adjusted based on log loss of what you submit finally, if you are in the top 20, thats what it says in the rules. So you have to keep track of your models and make it as reproducible as possible, like Chetan said :)

You're welcome
