Hello,

Following points will be really helpful if you try to work on it.

• Break the material down into small pieces.

It’s easier to process and remember information if you break it up into bite-sized chunks. Instead of trying to memorize an entire chapter of your textbook, focus on one short section or key piece of information at a time.

• Switch between different topics. It can be helpful to alternate between studying different subjects, so that your brain compartmentalizes the information more effectively. Switching between topics that are very different from each other can help keep your brain from getting bogged down with trying to remember too much about one subject (or 2 very similar subjects) at once. Additionally, switching between topics will help you avoid getting burned out on any one topic.
• Take notes.

As you’re listening in class or reading your text, write down important pieces of information. Don’t write down every word you hear or read. Instead, summarize key concepts. This will force your brain to process the information and condense it to its most important elements.

• Take breaks.

If you try to force yourself to study for too long in one sitting, you’ll soon start to nod off, or find your mind wandering. To make your studying more manageable and effective, try studying for an hour at a time. Take 5-15 minute breaks between study sessions to snack, stretch your legs, or put your head down for a quick catnap.

• Sleep on it.

Most people need 7-9 hours of sleep every night to be at their best. Getting enough sleep not only gives you energy and helps you concentrate, but it can also help you learn and remember. Your brain processes new information while you sleep, so you may find that you understand those difficult concepts better after a quick nap or a good night’s rest

Hey there

There is no formula or a short mantra which can help you remember What you read for long time. For all those things which do not entertain you will not be in your memory for long and so you'll have to revise it in short periods this is the only way to remember what you read. But if you'll start increasing interest in the subject you'll remember it for so long.

Good luck
