The four Quant topics you listed have more in common than it looks. Time, speed and distance, work, and simple and compound interest are all rate problems underneath. Once you're comfortable seeing a rate as a relationship between two quantities and setting that relationship up cleanly, whether in a table or a short equation, those three stop feeling like separate topics and start feeling like variations on one skill. Permutations and combinations is the outlier. That one is less about formulas and more about classifying the counting situation correctly, and most errors there come from reaching for a formula before deciding whether order matters and whether repetition is allowed. If you fix the classification step, the formulas take care of themselves.
Whatever resource you use, the thing that matters most is that it teaches each of these topics from the ground up and then gives you enough questions on that single topic to build fluency before moving on. Volume spread across all four at once will keep you feeling shaky in all four. Take them one at a time, work untimed at first, and push your accuracy into the nineties on a topic before you introduce any time pressure. When you miss something, name exactly what happened: a gap in the concept, a misread of the setup, or a careless slip. Those three require completely different fixes, and sorting your misses that way will do more for you than another hundred questions will.
On MSR, I think you've already diagnosed it correctly by noticing that you miss those questions even in content you're otherwise fine with. MSR is mostly an information management challenge rather than a content one. The material is spread across two or three tabs, the questions frequently require combining pieces from more than one tab, and many MSR prompts use the three statement format where all three have to be right for the question to count. A partial read gets punished hard in that format. The approach that works is to go through every tab first and build a quick map of what kind of information lives where before you answer anything. You're not memorizing the tabs, you're learning the layout so that when a question asks about costs or dates or capacity, you know immediately where to look. Then, for each question, decide which tab or tabs you actually need before you start reading closely. And since your DI misses cluster around the same topics you listed on the Quant side, the fundamentals work will carry over into DI on its own. Those two problems are less separate than they appear.
For a structured way through all of this, I'd point you to our TTP course. Each of the topics you named has its own chapter with the theory taught step by step and hundreds of practice questions at easy, medium, and hard levels, so you can take Permutations and Combinations or Rate Problems all the way from basics to advanced without hunting around for material. The Data Insights chapters cover MSR the same way, with the strategy taught explicitly and practice sets to drill it. You can try the whole thing for five days for a dollar and see whether the approach fits how you learn.
I hope that helps.

Hi all, I am currently having trouble with a few quant and data topics. I wanted to ask if you guys could recommend any resources to go to learn their fundamentals and basics, and then more advanced spaces as well.
In Quant =
1. Permutations and combinations
2. Time, Speed and Distance
3. Time and Work
4. Simple and Compound Interest
In Data, I am mostly struggling with questions that are related to the above mentioned topics but in terms of question type, Multi-source reasoning or MSR is the one that I keep getting wrong (even in topics that I am usually okay at)
Any suggestions or recommendations on how to work on these weaknesses?
Thank you!
