  Gujarat Secondary and Higher Secondary Education Board (GSEB) prepares the syllabus for SSC (Secondary School Certificate) and HSC (Higher Secondary School Certificate). The GSEB SSC examinations 2023 will be conducted in March. The GSEB evaluates the performance of the schools falling under the gamut of the State Board through frequent inspections besides granting recognition to the new schools. The GSEB SSC Time Table would include all the subjects including First language paper, Science and Technology, Mathematics, Social Science and Second Language (Gujarati) and will be released in January on its official website. To qualify, a candidate needs to score a minimum of 33%. Given below are some preparation tips for GSEB Class 10 exams: Make a Schedule and follow it It is important to follow a proper schedule while preparing for the exams. Sleeping and waking up early allows sufficient time to study during the day. Chalk out a proper schedule and allot time for each subject. This giv

   Exam 2022 : Science Important Questions with Solution (2 Marks) The science paper in  Class 10 Science Term 2 Exam 2022 will have the descriptive type of questions of different marks.  Section - B of the Class 10 Science paper will have 8 to 10 questions of 2 marks each. To help students score maximum marks in this section, we have provided below important 2 marks questions with solutions from all chapters of class 10th Science.  Students must practice all the chapter-wise questions to check their preparedness and revise important concepts for the upcoming exam. Chapter – 4 Carbon and its Compounds Que 1.  The element carbon forms a very large number of compounds. Give reason for this fact. Ans 1.  Carbon is the only element that can form so many different compounds because each carbon atom can form four chemical bonds to other atoms, and because the carbon atom is just the right, small size to fit in comfortably as parts of very large molecules. Que 2.  Covalent compounds generally

 10th  Exam 2022 : Science (Physics) Important Diagrams for Last Minute Revision We present here some important diagrams for Class 10 Physics. Many of the class 10 students find it difficult to grasp the concepts of Physics. However, if learned through diagrammatical representations, this subject is not all that difficult. This is because diagrams aid in visual learning which is more effective than simply mugging up the concepts by writing or reading. Each diagram has been provided with a detailed summary for a clear understanding. Important Physics diagrams for Class 10  are given below: 1. Verification of OHM’s Law Ohm's law states that under constant temperature, the current passing through conductor is directly proportional to potential difference applied across it. i.e., V = IR Where, V = potential difference R = Resistance (constant) I = Current Ohm's law can be verified using following circuit diagram, 2. AC Generator AC generator is a device which converts mechanical en
