How do I categorize polynomial data into five ranges

I'm pretty new to Rapidminer so I really don't know terms in relation to the software. I kindly ask for your understanding.

I have two columns, one is grades and the other is the descriptive remark of the grades. My problem is that I don't know which operator to use in order to categorize the grades. My expected output is that, once the grades have been categorized it will automatically put the results to the descriptive remarks column.

Here are the ratings:
0-35 - Very Low Mastery
36-65 - Low Mastery
66 - 85 - Average
86 - 95 - High Mastery
96 - 100 - Very High Mastery

I tried searching for YouTube tutorials and browse the community forum but I really can't find anything due to my lack of knowledge of terms in regards to Rapidminer.

    Hi @Goryeo ,
    have a look at the discretize operators. Likely Discretize By User Specification. Those should do the trick.
