This study investigated the effectiveness of an online learning environment (OLE) to practice for reading and listening for Cambridge English language tests in a restricted post-COVID situation using additional reading and listening materials. This mixed-method, exploratory research used a convenience sample (n=100) of students aged 11 to 15 in a Cambridge exam preparation centre to see OLE's effectiveness in improving their reading and listening. WhatsApp was used as a communication tool, while Zoom-based instruction and Google form-based formative assessment were administered in the OLE. Results revealed that the OLE was a convenient way to practice using extensive reading and listening materials, despite some infrastructure and digital literacy issues. Participation was high, and the results were excellent. However, a need to improve teachers' and students' basic computer literacy was observed. Limitations such as teachers' knowledge about online teaching tools and ethics of working with online pedagogy were identified as areas for further research.
