A professional is someone who does a job to earn money (not as a hobby) and can usually do that job well and with a high standard.

When you think or react logically, you think about them well, consider the facts and decide in a sensible way.

If you do things methodically, you so them carefully, in order and with a plan.

In a game or test, if you score, for example, five, it means that you get 5 points in that game.
Example:  She scored 140 on the IQ test.

A point in a game or sport, is one single mark that you get. For example It there are 10 questions in a test and the total mark is 20, it means that each question has 2 points.

If you concentrate on something, you give all your attention to it and only think about that thing (and not other things) at that time.
Example: I couldn't concentrate on my lessons because of the noise.

When something good happens or somebody has a success, for example when somebody has a baby or succeeds in the University Entrance Exam, you say "Congratulations!"

If something is decent, it may not be very good, but it is of an acceptable standard or quality.

If something is accurate, it is exact. For example if a watch is accurate, it shows the exact time.

The expression "to take something to heart" can be used in two ways:
1. When someone says something that affects you deeply and so you take suitable action to correct your mistakes. For example, your teacher criticizes you for not working seriously enough, and you take his criticism to heart and work harder.

2. When someone says or does something that upsets you very much and makes you feel unhappy. For example, a friend is angry with you and shouts at you and accuses you of lying. Later another friend tells you, "Don't take it to heart. He didn't mean it."
