The mod is right: you should post such questions in the right section.

However, I would like to say that maybe you are seeing the problem from the wrong angle.

Let me explain: RC passages repeat the same question over and over again, that passage change, the subject is different (history, science, humanity, so on)9 the questions are the same: main idea, inference, the role played by the paragraph or sentence, the passage as whole could be summarize by ...blah blah

The outline is always the same. No new deviations o are on the horizon....

For the GRE you could practice barely ten passages medium and another ten long and you are fine.

All that say what means: once you have shaped your strategy and this is tuned at its finest you do not need millions of passage to practice. You just need to read a passage and find the information they are in it

People instead practice over and over again...and over and over again repeat the same errors. more practice does not mean improvements but more often than not means repeating the same errors.

You need to refine your strategy and tune up your skills not more passages.

However, if you do need more: GMAT passages are great. gmatclub.com has all the OG GMAT passages. You do have Rc and CR for the next millennium.

Hope this helps
