-During my master's thesis\nbsp{}[cite:@vanpetegemComputationeleBenaderingenVoor2018] one of the goals was to allow the method I developed to work over many programming languages.
+My master's thesis\nbsp{}[cite:@vanpetegemComputationeleBenaderingenVoor2018] presented a method for estimating the computational complexity of solutions for programming exercises.
+One of the goals was to make it work over many programming languages.
 To do this, I wrote a framework based on Jupyter kernels[fn:: https://jupyter.org] where the interaction with each programming language was abstracted away behind a common interface.
-It was however, only developed as far as I needed for my master's thesis and thus served as a proof of concept for TESTed.
+We realized this framework could be useful in itself, but it was only developed as far as I needed for my master's thesis.
+It did however serve as a proof of concept for TESTed, which I will present in this section.
 
 TESTed was developed to solve two major drawbacks with the current judge system of Dodona.
 - When creating the same exercise in multiple programming languages, the exercise description and test cases need to be redone for every programming language.
