Engineering Entrance Exam

Give mock tests as much as you can and find the topics of strong and weak zone, and then take assistance from your teachers, seniors, juniors, etc. to cover your weak zone. Slowly but gradually increase your effective study hours. Last but not the least, don't let your preparation down.

According to me, there is no difference on BE and B.Tech. I can assure you that the courses are same in both of them. Difficulty level depends on the university and on the marking scheme.
Apart from this, practicals are there in the course but college fails to provide practical knowledge. A few institutes take students for industrial visits.

Yes, if you consider getting a good decent branch.

Hello Varsha,
I think you should start preparing for GATE exam in 5th semester then you can easily qualify for top colleges.
All the best.

It depends that which tuition you have joined. If you have joined a good tuition, then you don't need these things unless you go for it.

After scoring good rank in the exam, you are eligible for some top institutes of India.
Firstly, you should know your capacity, ability and patience as it plays a very important role in the exam. It can be done from anywhere until and unless you are hurry to get selected.
You can even prepare for it from home itself by watching NPTEL videos on YouTube.

There is a lot of difference between JEE and GATE. JEE is an exam conducted to get entrance to any engineering college whereas GATE is an exam conducted for entrance in PSU, or for M.Tech.

JEE is a tough exam and you must work rigorous and with proper guidance for that. It is possible to crack but without proper guidance, it would be difficult. Watch YouTube videos, solve old question papers, read good books like Arihant publications, HC Verma, RD Sharma, OP Tandon, Rasik and Halliday, NCERT, etc. Pradeep is also good. Join some good rest series by brilliant tutorials and FIIT JEE. You should be polite, humble and honest. Don't be arrogant and keep motivating yourself. Good luck.

Yes, you can as if you are an electrical or mechanical engineer then you get a chance to get job in the Indian railways, but you have to score good marks in the GATE exam.
