Let me share you guys a few tips to learn fast , which worked for me and so for you.

USE MUSICAL MNEMONICS 

Wondering what's that? nothing but to learn important topics which you forget easier by creating a song from it.

for example, take a book and learn a para from it and now play a song which is new for you, we remember the song better than the para learnt from book, so what sup singer, start singing your important topics. 

PRACTICE 

For math it's the best method I can suggest. Practice daily and Math will be your friend soon. Understanding would be great, try to understand what you learn.

WRITING DOWN THE IMPORTANT TOPICS

Yes, it will be tiring but success is not your fruit unless you work hard for it. Take a note and start writing. This would be a great helper during exams. 

One of the best memorizing trick I have ever known.

RECALL BEFORE YOU SLEEP

Reading before you sleep would help you to recall in exam, but make sure to recall in the morning. I have used this technique, it worked for me.

USE FLASH CARDS

I wish I had known this method earlier. No need to waste money, you can make your own flash cards, a skill activity.

BREAK

This is a must. Who doesn't need a break and our brain is no exceptional. The best break you would give your brain is doing meditation. 

some alternative break

(i)Intake fresh juice

(ii)listen to a song

(iii)take a walk

LEARNING A LANGUAGE

Yes, learning a new language is a best workout for your brain, give it a try you will definitely benefit by this technique. 

LESS USAGE OF PHONE, TV….

We are addicted to phone from the young ones till the grandparents use phone but do you know that it reduces you brain efficiency to focus on a particular work we do.

EXERCISE

Exercising helps you to refresh both brain. Daily exercising is a good thing which one can do to his both body and mind.

MINDMAP

If we talk about how to remember the topic we have learnt then we cant go without talking about Mind map. Our brain gets bored when we use the same square or rectangular boxes, instead try some curved lines, which your brain accepts faster than the normal ones

CONSISTENCY IS A KEY TO SUCCESS

DONT BE AFRAID TO FAIL, BE AFRAID NOT TO TRY
