Is tech skills a good school. I will be N+ and CCNA certified in 6 weeks is that posible?

School is not as important as the instructor.

Ask them:

Do I have one instructor for all 6 weeks?

Can I talk to my instructor(s)?

What courseware will we be using?

Personally, I have not heard any good or bad things about them. Even if people have, you might get a different instructor anyway….

I know nothing about the school in question but yes you can be accredited with those two IT certificates within 6 weeks…it just takes lots of dedication and studying. Good luck in your endevaours.
