For Bengali, I’d advise you to do the following:
- Download and read carefully (learning the translations, idioms, etc.) the Edexcel IGCSE Bengali Specification
- Download and read the Edexcel IGCSE Bengali Teacher Guide
- For a thorough practice for Question 1, which consists of the translation of 5 Bengali sentences to English, you can sit and practice as many of those as possible from past papers. Although I haven’t come across any repeats, I still found it helpful to pick up vocabulary from those. It’s also a great boost to your confidence and definitely something to do when you don’t feel like doing the longer passage translations.
- For Questions 2 and 3, practice past papers and highlight the words unfamiliar to you, list them down and learn them up.
- Make a list of topic specific পরিভাষা / terminology such as those based on Earthquake, Environment, Global Warming, Seasons, Professions and other common and recurrent topics. This will also help in your essays.
- Read some sample essays from easy essay books or skim through them actually. (Because this doesn’t help much).
- Brainstorm points for essays and list them, if you find yourself too lazy to write out essays properly.
- For past papers, you can use the Edexcel website
- For Bengali revision and tips online, Shawon Notes may also prove to be a helpful source.
Hope these help you in your prep!
