Hello,
Here is the link where you can get required question paper : GATE 2024 EE Question Paper
Hope it helps !
If you are needed to prepare for gate exam from ece batch there 65 questions in exam pattern total marks is 100 here 15% is aptitude general questions then 15% mathematics engineering questions , 70% core subjects you need to concentrate on more core related subject like controls system , signals and system , digital circut these topics covers most of the basics but you need to prepare more topics in core subjects and create a structure plan for yourself dialy attend mock test with time duration these steps will help to prepare very easily.
Hello,
So, according to your first question, you want to know specialization in chemical engineering for M.Tech after completing the B.Tech program. Here are some good specializations for the M.Tech program
Also, for the second one, you want to know some good colleges that allow management quota for admission in private options. Here are some
I hope it will clear your query!!
