How do you cope with challenges you face with speaking English?
Here is a summary of my coping mechanism:
1) Don't overcomplicate the way in which a point is said. Rather, enrich it by adding more evidence.
2) Instead of thinking in simple sentences only, try using compound and/or complex logic. i.e. try to construct such logic by using signposts of a compound/complex sentence e.g. but, so, although.
3) Be conversational (even if in speaking tests), and thus remind myself of how naturally good I am at English.
