Maths Spl

I am not sure about physics, but surely you can combine maths with your humanities subject. If you have economics in your humanities subject then maths as an additional subject can definitely prove to be a boom for you. Knowledge of core mathematics is highly necessary for understanding the advance theorems of Marco-Micro economics. When it comes to the understanding the concept of consumers producer behaviours, price determination, revenue recognition, etc., you must have the knowledge of matrices, differentiation & integration, statistics and probability. These concepts help a lot while having an advanced and realistic knowledge of economics (as a part of humanities). So, in this way, we can relate the subjects of maths and economics. Here, physics may not help you much (since physics is the application of mathematics in the practical world), but it may help you to enhance your mathematical calculation skills. Hope this helps.
Best of luck.

Hello,
If your study for 4 hours and understand the logic and concept instead of studying for 10 hours just "solving problems" the former will yield definitely more marks than the later.
As maths is almost every time easy (if you have interest) in JEE comparing to others. So, I suggest in order to cover it in a limited time frame follow these steps.
Every day before starting draw out a rough plan of what topics you will cover today pointwise.
Then start working on it and as I said before whatever you do understand the logic of it and only then do it else leave it because it will be a waste of time otherwise. Once you are 100% sure you have understood the topic solve its primitive examples.
Then pick 10 problems related to the same topic and all should be of different type and varying difficulty. Solve those 10 problems and then look at your rough plan and jump to the next topic. In between do take breaks or else you will get bored soon and scrap the whole plan.
All the best!
