DB_DATABASE=laravel_app
DB_USERNAME=root
DB_PASSWORD=root

Open Migration file and write this complete code into it.

     * @return void
     */
    public function up()
    {
        Schema::create('students', function (Blueprint $table) {
            $table->id();
            $table->string("name", 120);
            $table->integer("term1_marks");
            $table->integer("term2_marks");
            $table->integer("term3_marks");
            $table->integer("term4_marks");
            $table->text("remarks");
        });
    }

    /**

     *
     * @return void
     */
    public function down()
    {
        Schema::dropIfExists('students');
