JLPT N5 level
Will it be quite difficult to do good in JPLT N5 exam if I study using online resources ( like YouTube, Duolingo) only? Can someone suggest me a few sites which will help me for JLPT exams?
There are a few resources online. Suggest you take look at as many as you can and bookmark the ones you find mesh best with your learning style and that you find most enjoyable.
That has been discussed on other posts. It really depends on what your intentions are. It could be a good motivational tool for you and put you in an environment with other language learners. That being said, the N5 through N3 certifications have dubious real-world value. If, however, you intend to eventually take the N2 or N1, it might set help you on your path by giving some structure and recognition of your effort.
