Yes, all the tenses hold equal importance in competitive and entrance exams. While some tenses such as the Present Tense and Past Tense appear more frequently in English grammar questions, understanding and studying all the 12 types of tenses in English ensure better comprehension and accuracy. Various questions on fill in the blanks and setence correction, include questions on tenses. 

Students can refer to the following books to study and understand the topic of complex sentences in English:

Following are the examples of complex sentences:

After you work is done/join us at the restaurant for the dinner.

Dependent clause/Independent clause

Although she was tired/but/she went for shopping.

Dependent clause/conjunction/Independent clause

Because/ it was hot/we did not go out.

Subordinating conjunction/ Dependent clause/ Independent clause

When a sentence contains one or more Dependent clauses along with multiple independent clauses, it becomes Compound Complex Sentences. Ex: Because it was raining, the children stayed inside, and they played board games.

Remember, the complex sentence only has one independent clause and one or more dependent clauses. Ex: When the party ends, we can go home.

A Complex Sentence is a combination of an independent clause (which can stand alone as a sentence) with one or more dependent clauses (which cannot stand alone). These clauses are linked using subordinating conjunctions like "because," "although," "while," "since," or relative pronouns like "who," "which," or "that". Unlike Simple Sentences, Complex Sentences are not complete in their thought until both the clauses are used.
