Best Study Tips To Get Better Grades (According to me)

Need study tips? Are you struggling to keep up in class? When you study you don't feel you learn much or anything at all? Getting better grades? Being more prepared than others?

Well. Me too.

So I did these things.

1- SING OUT LOUND! No, Wait! My brother does that. It's Read Out Loud

Be YOUR OWN TEACHER. Why? Good question, perhaps one of the reason can be MY TEACHER LEAVES THINGS OUT.

- Speaking the content out loud helps you to understand it better. Reciting out the words in YOUR OWN WORDS helps a lot. You learn aspects and even learn it far better than when you read a book. - When you speak the lesson or chapter out loud you are processing it as you speak. Think of it like you are giving a speech. Don't you want your speech to be as effective as possible? And how do you make it so effective? By getting authentic information of course!

2-Flash notes.

Make flash notes. The best time to make them is as soon as a new chapter starts. If you are an Edexcel or Cambridge student, I'm sure you will understand just how important the specification is. Even the books has topics at the start of every chapter.

Use each point to make relevant notes on the specifications, this way you can easily know which main points of the topic if stated. Making these flash notes also help you revise and learn as you make them.

Let me know if you wish to know how to best make Flash Notes.

I will make sure to use an example and help you make them as well as link sites to help you better.

3-Practice Makes Perfect Or So They Say.

Hold it! Stop! Don't hit that back button just yet. This is annoying. So annoying but so desperately needed. You can't get good at Math with doing only one question a day. You need to practice, practice and practice. Study the concept, the method, relevant keywords. Know it so well you can dream of them and write them in your sleep. YOU NEED IT.

Math - those one-page questions need to be practiced at least 3-4 times until you learn it well enough. It seems like a lot of effort, and at times too much to handle and Math is like that but from a person with experience, doing just one question a day can take you up the ladder of improvement. Physics - questions need a to be revised and checked, especially those that voice out the same question. The question maybe same but they may have a different method of getting the answer. Chemistry - REVISE THE EQUATIONS. Think of the equations as the key aspect to breathing. One single thing wrong you lose a mark. AND EVERY MARK COUNTS. Biology - KEY TERMS. Key terms are so important, you have no idea. You cannot go in a Biology exam without those terms. At times the teachers won't even tell you those terms, So, those terms are so important you have no idea.

If you want to understand this better, do let me know. I will do my best to help you understand it better.

4-Past Papers.

Once while doing a paper I was quite confident I would pass, until I got my paper back. Not only was my score low, but it was low due to certain answers not accepted by the paper. How come? They were the same points my teacher had told me about. Everything she taught, then why the low grade? Simple, because she never mentioned the answers that will be accepted in the paper. Some of the answers were never taught in class. Often times teachers do not mention certain points that are relevant to the papers and so students lose marks.

By attempting the papers, you understand what the examiner is looking for and how to best attempt the questions.

Tip: Pay attention to the reject part of the marking scheme. They help you understand the paper pattern and how best to assess the paper.

5-Make Note of The Hard Questions.

When you see that one question with at least 6-7 or 10-12 marks. NOTE THEM DOWN. Why? Simple they aid you when you need them most. Best example I have for you if the most recent one I did.

When studying for Chemistry Unit 5, those questions with even 5 marks that seem really important and you have not done in class before, have them in a note book. This lets you know what can and will come in the paper and how you must asset them.

Say that question where you must find the sides of the shape in Math. Trigonometry questions, find base from plane, those find the “X” question and many more. If you cannot solve them or have trouble solving them and are taking a long time. NOTE THEM DOWN.

Have it in a notebook, with question and answer. Make it so when you come to revise later you can understand and figure out a way to gain those marks more easily.

I hope all this helps.

Black Holes: Seeing the Invisible!

Black holes are some of the most bizarre and fascinating objects in the cosmos. Astronomers want to study lots of them, but there’s one big problem – black holes are invisible! Since they don’t emit any light, it’s pretty tough to find them lurking in the inky void of space. Fortunately there are a few different ways we can “see” black holes indirectly by watching how they affect their surroundings.

Speedy stars

If you’ve spent some time stargazing, you know what a calm, peaceful place our universe can be. But did you know that a monster is hiding right in the heart of our Milky Way galaxy? Astronomers noticed stars zipping superfast around something we can’t see at the center of the galaxy, about 10 million miles per hour! The stars must be circling a supermassive black hole. No other object would have strong enough gravity to keep them from flying off into space.

Two astrophysicists won half of the Nobel Prize in Physics last year for revealing this dark secret. The black hole is truly monstrous, weighing about four million times as much as our Sun! And it seems our home galaxy is no exception – our Hubble Space Telescope has revealed that the hubs of most galaxies contain supermassive black holes.

Shadowy silhouettes

Technology has advanced enough that we’ve been able to spot one of these supermassive black holes in a nearby galaxy. In 2019, astronomers took the first-ever picture of a black hole in a galaxy called M87, which is about 55 million light-years away. They used an international network of radio telescopes called the Event Horizon Telescope.

In the image, we can see some light from hot gas surrounding a dark shape. While we still can’t see the black hole itself, we can see the “shadow” it casts on the bright backdrop.

Shattered stars

Black holes can come in a smaller variety, too. When a massive star runs out of the fuel it uses to shine, it collapses in on itself. These lightweight or “stellar-mass” black holes are only about 5-20 times as massive as the Sun. They’re scattered throughout the galaxy in the same places where we find stars, since that’s how they began their lives. Some of them started out with a companion star, and so far that’s been our best clue to find them.

Some black holes steal material from their companion star. As the material falls onto the black hole, it gets superhot and lights up in X-rays. The first confirmed black hole astronomers discovered, called Cygnus X-1, was found this way.

If a star comes too close to a supermassive black hole, the effect is even more dramatic! Instead of just siphoning material from the star like a smaller black hole would do, a supermassive black hole will completely tear the star apart into a stream of gas. This is called a tidal disruption event.

Making waves

But what if two companion stars both turn into black holes? They may eventually collide with each other to form a larger black hole, sending ripples through space-time – the fabric of the cosmos!

These ripples, called gravitational waves, travel across space at the speed of light. The waves that reach us are extremely weak because space-time is really stiff.

Three scientists received the 2017 Nobel Prize in Physics for using LIGO to observe gravitational waves that were sent out from colliding stellar-mass black holes. Though gravitational waves are hard to detect, they offer a way to find black holes without having to see any light.

We’re teaming up with the European Space Agency for a mission called LISA, which stands for Laser Interferometer Space Antenna. When it launches in the 2030s, it will detect gravitational waves from merging supermassive black holes – a likely sign of colliding galaxies!

Rogue black holes

So we have a few ways to find black holes by seeing stuff that’s close to them. But astronomers think there could be 100 million black holes roaming the galaxy solo. Fortunately, our Nancy Grace Roman Space Telescope will provide a way to “see” these isolated black holes, too.

Roman will find solitary black holes when they pass in front of more distant stars from our vantage point. The black hole’s gravity will warp the starlight in ways that reveal its presence. In some cases we can figure out a black hole’s mass and distance this way, and even estimate how fast it’s moving through the galaxy.
