Hello,

If you are worried about score, then first thing you have to do is to calm down. Score won't come if you get anxious.

1. If you have prescribed book which is needed to prepare for entrance exam then that much will do.
2. Start from easy chapters. Solve examples and chapter end questions. there is solution to everything.
3. Solve and look for solution. check if it is correct. if you get wrong then solve it again next day morning or evening. Keep on progressing.
4. Go from easy to hard and wrong to right.

There is no shortcut to success. It is only hardwork to get it. Practice as much as you can. Take help of friends and youtube lectures if necessary.

Hope it helps!

Hello there!

To find  Inflection points you need to know that inflection points  are located one standard deviation above the mean and one standard deviation below the mean , so for any normal curve , you can easily find points of inflection , you  can find the x-values for the points of inflection  by subtracting the standard deviation from the mean and adding the standard deviation to the mean to get the two x values for the points of inflection.
