Yes, you must take the TOEFL or IELTS. You must also submit a very good SOP/CV/resume too.

I don't know about TOEFL, this exam is of 100 marks and for IELTS there is overall 9 bands (0-9). Most of the colleges ask to score above 7 bands in this exam. There is no criteria for level 1 or 2. If you take any coaching (especially for IELTS or TOEFL).

Hi Pratiksha,
If your English is not strong plus if you are planning to study abroad I will strongly advice you to improve your English communication skills. How will you converse with students and how will you sustain the English speaking environment if you are not well-versed with the language of communication. Nevertheless you will need an all-rounded good performance in your test to pass the TOEFL decently.
