Things must be taken one step at a time and repeatedly, for both Physics and Mathematics. You’ll be more confident when you do it more. Math is inseparable from Physics. Not to sound discouraging but you cannot do well in Physics if you are weak in Mathematics!
However, there are ways to improve and do better. Below are a few tips that could work:
1. Take your time
Learning Math takes time as every topic in it requires a decent amount of knowledge of the previous ones since they just build on each other. If you’re having a problem with a topic now, ask for help and continue practising until you understand better.
Try not to move on to another topic without mastering the one on hand. You’ll only get more frustrated.
2. One step at a time
One common problem in those with weak math skills that is persistent in their Physics performance is that they try to solve the question in their heads without writing anything down.
What you need to do is, take it one step at a time. Start by writing down the problem, including the simple things. Deal with the problem in small segments. This will make things easier for you to check your errors, if any.
3. Draw a picture of the problem
Applicable to both Math and Physics, it is supported by many IP tuition in Singapore as we are visually inclined. We can internalise and digest a problem well if we draw it out, no matter how roughly approximated it is. It is not a matter of Physics or Math; drawing will make things easier to carry on.
