Whether it’s the C2030-283, C2090-540, or any other in the IBM series, there will be some combination of direct resources or overlap with other material. So, as we said above, the first place we’d look is Amazon using the links we gave as a shortcut/jumping off point to find related exam materials. Next,
see if Pearson has any that apply to the cert you’re targeting. Last, you can
take a look Udemy for other video courses, practice tests, lectures, etc. The quality is hit or miss, but you can find some gems.
