BITS-HD provides prominence upon the questions related to theory. However, in GATE the emphasis is given to Numeric related questions. 

Examination Pattern:

• In 120 minutes, the students are given a total number of 100 questions to be solved. 
• The pattern of this exam is somewhat similar to the IES. 
• You should look through the previous year question papers of the IES paper thoroughly and do the same with the GATE papers. 

Syllabus:

• Focus more on clearing your concepts for important topics of Mechanics. 
• BITS-HD syllabus has more topics when compared to that of GATE. Prepare well for the whole syllabus. 
• The first paper covers Mathematics and English. Try to do well in the 1st paper. It is quite scoring and with sufficient preparation, you can even score the full marks. This will give you an edge over the others. 

Try to score close to 190 to secure a seat in your preferred branch. Hope this was helpful.
