GATE 2018 Life Sciences (XL) Paper was successfully held on February 3, 2018. The paper consisted of general aptitude and conceptual domain knowledge in about 65 questions carrying 100 marks, of which 10 questions will be based on general aptitude and the remaining questions would be based on the subject. Here is a brief look at some of the important takeaways for GATE 2018.
The Official GATE 2018 Answer key and Question Paper has been released –

Post declaration of results, GATE Participating Institutes will announce their separate GATE Cut Offs. On the basis of GATE cut offs, the participating institutes (other than IITs, NITs, CFTIs) will release their merit lists for admission through GATE.
GATE answer keys with correct solutions to the Life Sciences (XL) question paper, among other papers will be published on the official website, by the examination authority soon after the scheduled exam date. Candidates can access their individual response sheets through candidate login on the GOAPS (GATE Online Application Processing System), to check the answers that they submitted in the exam, against the official answer keys.
Candidates can access, download and check their GATE response sheet, question papers and answer keys for each paper/subject, session-wise, estimate scores and also file objections to the answer key through their individual login in GOAPS.
GATE Response Sheets are the individual candidates’ answers to the questions in the GATE papers. Candidates can access their individual response sheet in the following steps:
GATE Answer Keys will contain the correct solutions/answers to the questions asked in the GATE Papers. Please note that the Answer Keys will be released provisionally in the first place, and later released with changes incorporated (if any) on the basis of valid challenges from the candidates. Candidates can access their subject-specific Answer Keys in the following steps:
Candidates have the option of raising objections to the answer keys released provisionally. The steps involved in doing so are listed below:
Candidates can estimate their GATE Score using the Answer Key in the following manner:
|1 Mark Question||2 Mark Question|
|MCQ||+1 for Correct Answer -1/3 for Incorrect Answer||+2 for Correct Answer -2/3 for Incorrect Answer|
|NAT||+1 for Correct Answer||+2 for Correct Answer|
|GATE Score||MCQ Score+ NAT Score|

GATE 2018 Cut off score is the minimum score that candidates need to secure in order to qualify the entrance test. Note that GATE Cut Offs will be separate for qualifying the exam and for admissions. The admissions cut-off will vary for each participating institute as it is dependent on the number of seats available at a particular institute as well as the number of applicants therein.
Here we have tabulated the qualifying marks for the Life Sciences paper from the last three years. Candidates should bear this in mind that the Qualifying Cut-off will vary on the basis of the difficulty level of exam and the total number of applicants.
