The JSTS process starts in August/September where you have to fill in a registration form and send it to the Directorate Of Education.
The first level paper is divided into 2 parts. The first part is a 1 hour GK paper which tests your knowledge of GK, current affairs etc. It is a 50 marks paper. More importantly all the questions in the first level paper are MCQ type in the first level with each question for 1 mark each (except some questions in GK) there is no negative marking. It is generally easy and can be very scoring. The Gk paper is important as the GK paper can give you a little edge over the majority.(Obviously for this you have to be in tune with the current happenings all over the globe and about facts in India) . There were about 20 MCQs , 20 questions where the student would have to supply his own answers in 1 sentence or 1 word and there were 10 questions based on symbols of famous companies, government organisations, political parties, universities, sporting events etc. For preparation go through your old history books, read newspaper daily, observe all the logos of the governmental organisations and use Wikipedia thoroughly. Manorama Yearbook may help too. All the answers have to be supplied in the question booklet itself.
The next level paper is a 2 and a half hour paper that tests your Maths and Science. There are about 25 questions in Maths and 50 questions each in Physics, Chemistry and Biology. 175 marks in 150 minutes.
