what are the other exams other than gate

Aditi Amrendra Student Expert 15th Oct, 2019

If you looking for Job then the best alternative for GATE exam is the UPSC IES examination which is conducted for engineering graduates.This is the best way possible you can get a job and that too in government of India and also there is a long list if perks and perquisites you will get once to crack IES examination.

I hope this helps.

Hi, Regarding Gate application correction form, right now there is no option to upload my photo. Now, what to do sir? how should I upload my photo now? Thanks in advance.

Vishwaksen Gouda Student Expert 15th Oct, 2019
Hie manali,
You can upload the photo again even after the closure of the gate application submission.High quality image must be uploaded in the application.Background and sign should be white.Reuploading facility is also will reopen and you can upload

Now Im 3 year of btech Cse. How I can prepare for a gate exam?

Priyaanka Sarkar Student Expert 15th Oct, 2019

As you are still in your 3rd year, you might not be still aware of the complete GATE syllabus. So analyse the topics and syllabus that you have learnt for the past 3 years and practise as much Mathematics as you can. Try as many mock tests as possible and get a hang of the exam pattern. Please check our page for syllabus, topics and best books for preparation:


Hi, Regarding Gate application correction form, right now there is no option to change my category details. Will it be provided in the future? I had incorrectly selected GEN, but it is OBC/NCL. Thanks in advance.

Priyaanka Sarkar Student Expert 15th Oct, 2019

Dear Harish, IIT Delhi has scheduled diiferent correction windows for different correction categories. The tentative dates to make corrections to your Category would be from the last week of October to 1st week of November. This is tentative and so please keep an eye on the official website. You can change your Category but you will not be refunded any additional amount that you paid towards your application form. For more information, please visit our page at:


can I apply for the gate exam now?

Priyaanka Sarkar Student Expert 15th Oct, 2019

Dear Pramod, IIT Delhi has closed registrations for GATE 2020 as on October 5th, 2019 along with late fees. Now the correction window has been opened. At this juncture, registering for GATE 2020 is not a possibility. You may have to wait until the next year if you  plan on appearing for GATE. For GATE 2020, you have been late.
