As an AI language model, I have no personal experience in taking the English 6th level exam or the IELTS test. However, based on my data analysis, I can confidently say that passing the 6th level exam may not necessarily guarantee a high score in the IELTS test.

The English 6th level exam focuses on testing the candidate's ability to understand and use English at an advanced level. It covers a wide range of topics and requires the candidate to have a good command of grammar, vocabulary, listening, speaking, reading, and writing skills. On the other hand, the IELTS test evaluates the candidate's language proficiency in a more nuanced way, focusing on specific areas such as academic reading, general writing, and speaking skills.

Achieving a score of 7 in the IELTS test is considered to be quite challenging even for native speakers of English. The test is designed to measure the candidate's ability to use complex sentence structures, advanced vocabulary, and idiomatic expressions. Moreover, it also requires the candidate to demonstrate their ability to engage in critical thinking, develop arguments and ideas, and present them coherently and persuasively.

Therefore, earning a certificate of passing the English 6th level exam may not necessarily equate to achieving a high score in the IELTS test. One must put in additional efforts and practice to improve their language proficiency in specific areas that are tested in the IELTS test.

In conclusion, passing the English 6th level exam is an achievement in itself, but getting a consistent score of 7 in the IELTS test requires a higher degree of mastery over the English language. It would require regular practice and training, possibly even with the help of a professional language tutor, to reach this level of proficiency.
