This combined edition brings all three volumes of the BBC Janala English-learning course together in a single book. BBC Janala was created to help Bengali speakers learn practical English step by step, and this omnibus lets a learner move from the first volume through the third without switching books. Published by Prothoma Prokashon, ‘BBC জানালা: ইংরেজি শেখার বই (তিন খণ্ড একত্রে)’ is a study companion for self-learners, students and anyone who wants a structured path to everyday English. Having the whole course in one place makes it easy to revise earlier lessons while progressing to more advanced ones.
