I listen native sounds all days, but I don't improve my listening skills.

I tried to take a tentative exam for TOEIC on YouTube.

As a result, I didn't understand about a half of audio between part 1 and part 4.

Although I've been keeping studying English in my holidays and free times, I was reluctant to my talent.

I wonder this problem will resolve some day if I continue to learn English consistently.

Can I obtain the certificate of CISSP in English for my next career?

I want a certificate of cybersecurity fields.

So I also learn about it's technologies at same time.

I only have a limited time for my next career because I'm already 40 years old soon.

I can't remain a novice or an apprentice.
