The exception of the degree, "the degree is a very important part of competitive exams English" where every exception is a milestone of English grammar.

Without an adjective English grammar can not be framed, adjective play a very vital role in English, students just cram the meaning of words but they haven't an idea that every word has its definition and rules to use, 

As I said every word has its definition and uses, for example, "Deep fake" is a noun, that stands for video of a person in which his face or body has been digitally after.

Thus students have to understand the value of "degree" A degree is part of an adjective that refers to the intensity of a word in three different categories which are known as POSITIVE DEGREE COMPARATIVE DEGREE, AND SUPERLATIVE DEGREE, degrees can be used differently in sentences.

POSITIVE DEGREE; A positive degree is used for one person or thing,

COMPARATIVE DEGREE; is used for two,

A SUPERLATIVE DEGREE; is used for more than two persons or things.

Now, be aware of  yourselves that a degree has 6 exceptions that help in forming sentences correctly, 

The aspirant must know of them, 

Exception 1, after 'than either subjective case or objective case can be used, but all in all it depends on the structure of the statement, 

Let's have a look at the sentences,

Ex; She is taller than l.

Ex; She likes him more than me. 

The logical point is that the comparison should be in an equal position,

Subjective cases can be compared with subjective cases, and objective cases can be compared with objective cases.

Exception 2. "Verb of sensation" There are six senses in human beings & verbs related to them, are known verbs of sensation.

Just remember that after the verb of sensation, only a positive degree is considered right.

Ex; The food smells delicious.

Ex; She feels bad for him.

Exception 3. Some adjectives are not used "than" after them, and' to' is used aftethenan, Mostly in concept is enforced with ending letters, ior & or. 

Here are a few words to make you acknowledge, senior, junior, prior, minor, Superior, anterior, interior, ulterior, exterior, & posterior.

Ex; She is junior to me in the class.

Ex; He is very senior to me so, I can not defy her order.

Exception 4. Some adjectives can not be intensified with more, very, much, or most.

Here, they are,

Unique, extreme, excellent, complete, perfect, final, last, universal, absolute, impossible, & etc.

Ex; The diamond is the most unique metal in this world.

The sentence should be,

Ex; The diamond is unique mental in this world.

Exception 5. Some conjunctions play a very important role in forming the statement correctly. It can be a short trick to understand the terminology of English.

"And" is one of them which stands for the equal forming of words,

When in a sentence 'and' is used just keep in mind that either degree or verb is used before "and" after and the same degree or verb should be used.

Ex; He is getting better and better at his work which makes him an eminent employee among us.

Ex; She boils the water and keeps it in the fridge.

Exception 6. When two persons or things are compared to each other then the "comparative degree is used & before the comparative degree "article is placed.

Ex; He is the younger of the two brothers.

Ex; She is the older of the two sisters.

That is all about the exception of the degree, these exceptions stand for the aspirants who are going to face or will face competitive exams.
