Comparison operators:

== (equal to), != (not equal to)
< (less than), > (greater than)
<= (less than or equal), >= (greater than or equal)

Logical operators:

AND, OR, NOT

String operations:

string.length - length of string
string.substring(start, length) - extract characters
string.upper / string.lower - change case

This study notes covers Deep Dive: GCSE Pseudocode Conventions within Trace Tables for GCSE Computer Science. Revise Trace Tables in 3.1 Fundamentals of Algorithms for GCSE Computer Science with 15 exam-style questions and 8 flashcards. This topic shows up very often in GCSE exams, so students should be able to explain it clearly, not just recognise the term. It is section 5 of 8 in this topic. Use this study notes to connect the idea to the wider topic before moving on to questions and flashcards.
