Hello ivy18, welcome to the forum.
May I suggest you read the information on this page:-

As you can see from the last sentence. There is no other way to secure points.
Must have an approved sponsor and must have enough money.
Be very cautious of any agents who will charge you money. Unless you get the appropriate certificate from a licensed UK sponsor you will be wasting your money.
Sorry to say this.
